Yoga is an ancient practice with deep roots in India, designed to bring balance to both the mind and body. Through a mix of movement, mindful breathing, and meditation, yoga supports overall well-being from the inside out. With many styles and paths to explore, yoga offers something for everyone—whether you're seeking physical strength, mental clarity, or inner peace.
In this guide, we'll journey through yoga’s rich history, core philosophies, powerful health benefits, and the many branches that make it such a diverse and meaningful practice today.
1. What is yoga?
1.1. True definition of yoga
What is yoga, really? Ask ten different yogis and you’re likely to hear ten different answers. That’s because yoga has evolved into a rich, diverse practice—blending ancient wisdom with modern interpretations. Today, yoga is expressed through countless styles, branded programs, and approaches, each reflecting the unique experiences of those who practice it.
At its heart, yoga is a physical, mental, and spiritual discipline that traces its roots back to ancient India. The term “yoga” comes from the Sanskrit word yuj, which means “to yoke” or “to unite”—symbolizing the deep connection between body, mind, and spirit. While the sage Patanjali famously codified yoga in the Yoga Sutras around 400 C.E., the tradition itself was passed down from teacher to student long before it was ever written.
Originally shared through intimate, one-on-one mentorships, yoga has grown into a global movement. Group classes, online flows, and even apps now bring yoga poses and philosophy to people of all walks of life. From gentle stretches to powerful asanas, the physical side of yoga is just one gateway into a much deeper journey.
Despite the many styles—from Hatha to Vinyasa to Kundalini—most forms of yoga aim toward the same purpose: inner peace and freedom from suffering. Through conscious movement, breathwork, and mindful awareness, yoga helps align our energy, quiet the ego, and open the door to a more awakened way of living.
1.2. What is at the Heart of Yoga?
At the core of yoga lies something far deeper than just yoga poses — it’s a path toward union. In fact, the word “yoga” itself comes from the Sanskrit root yuj, meaning "to unite". This union refers to the connection between our individual consciousness and the greater universal Spirit — a state of blissful awareness beyond ego, fear, and suffering.
Since ancient times, meditation has been the heartbeat of yoga practice in India. More than a method of relaxation, it’s seen as a precise science — a step-by-step inner journey that helps us dissolve the distractions of the mind and awaken to our truest self.
One of the most profound paths in this journey is Raja Yoga, also known as the “royal path.” Raja Yoga offers a complete spiritual framework that includes ethical living, breath control (pranayama), deep concentration, and meditative stillness. These teachings were preserved and passed down through India’s ancient spiritual tradition, known as Sanatana Dharma — the Eternal Way.
Among the most revered meditation systems is Kriya Yoga, a sacred technique of energy and breath control. Though mentioned in ancient texts like the Bhagavad Gita and Yoga Sutras of Patanjali, the detailed method of Kriya was hidden from the public for centuries — until it was reintroduced to the world by a lineage of enlightened masters: Mahavatar Babaji, Lahiri Mahasaya, Swami Sri Yukteswar, and finally, Paramahansa Yogananda.
At the heart of his teachings is the daily practice of meditation. When practiced regularly, this stillness brings us home to our true nature — a state of inner peace, unconditional love, and boundless joy that remains untouched, no matter what life throws our way.
2. The history of Yoga
When you hear the word “yoga,” do you imagine flexible bodies, deep stretches, or peaceful breathing? You’re not wrong — but you’re only seeing one petal of a much larger lotus.
Yoga is not just a workout. It’s a way of life. An ancient spiritual practice with roots stretching back over 5,000 years, yoga blends physical movement, breath control, meditation, and ethical living into a complete system for wellness and self-realization. It unites body, mind, and soul — guiding practitioners toward inner peace, clarity, and liberation.
The word “yoga” comes from the Sanskrit root yuj, meaning “to yoke” or “to unite.” At its core, yoga is about connection — between the self and the universe, the body and breath, the mind and the present moment. From India’s sacred mountains to modern studio floors, yoga has evolved into countless forms, but its essence remains: to bring balance, harmony, and meaning to our lives.
Those who reach this deep sense of connection are said to achieve moksha — freedom from suffering and oneness with universal consciousness.
2.1. The Evolution of Yoga Through the Ages
The Vedic Origins of Yoga (c. 1500–500 BCE)
Yoga's story begins over 3,000 years ago, amidst the sacred chants and fire rituals of the Vedic civilization that flourished in north-western India.
While there is little archaeological evidence to pinpoint the exact origins of yoga, early references to yogic-like practices appear in the Rig Veda, the oldest of the four Vedas. These hymns speak of long-haired ascetics—proto-yogis—living on the fringes of society, absorbed in deep meditation and mystical states.
But yoga, as a spiritual path and systematic discipline, began to crystallise much later—around 1000 BCE—through a body of philosophical texts that would forever change Indian spirituality: the Upanishads.
The Upanishads: Yoga as Spiritual Inquiry (800 BCE–500 CE)
The Upanishads are bold, poetic treatises that delve deep into the nature of consciousness, reality, and the human soul. They introduced central yogic ideas—such as the unity of the self (Atman) with the Absolute (Brahman)—and laid the foundations for India's spiritual traditions.
The Katha Upanishad defined yoga as "control of the senses and cessation of mental activity."
The Maitrayaniya Upanishad outlined a sixfold yogic path including pranayama, pratyahara, dhyana, dharana, tarka, and samadhi.
These teachings marked a turning point, evolving yoga from ecstatic mysticism into a structured inner science of liberation.
Classical Yoga: Patanjali and the Systematisation of Practice (c. 200 BCE–200 CE)
As yoga matured, it entered its classical phase, distinguished by an emphasis on system and discipline. This era reached its philosophical zenith with the Yoga Sutras of Patanjali—arguably the most influential text in the yoga tradition.
Patanjali’s Ashtanga Yoga (Eight-Limbed Path) laid out a detailed roadmap to spiritual awakening:
Yama – moral restraints
Niyama – personal observances
Asana – steady posture
Pranayama – control of breath
Pratyahara – withdrawal of senses
Dharana – focused concentration
Dhyana – meditative absorption
Samadhi – transcendental bliss
While modern yoga often emphasises asana, Patanjali gave more space to meditative and introspective practices. His goal was progressive interiorisation—a turning inward that culminates in union with the Self.
Post-Classical Yoga: Hatha, Bhakti, and the Yogas of Devotion (500 CE–1800s)
The centuries following Patanjali’s work saw yoga diversify into multiple paths, each suited to different human temperaments. These systems remained rooted in the same core aim: liberation (moksha), but adapted their methods for broader accessibility.
Hatha Yoga: Emphasising bodily purification, Hatha Yoga emerged as a more physically focused path. Though ascetic and rigorous, it paved the way for the asana-centric styles popular today.
The Bhagavad Gita’s Triple Path: The Bhagavad Gita, a sacred epic from this era, reimagined yoga as something integrated into daily life, presenting three powerful paths:
Karma Yoga – selfless action without attachment
Bhakti Yoga – devotional love toward the Divine
Gyana Yoga – pursuit of wisdom and insight
Modern Yoga: From Indian Revival to Global Movement (1800s–Today)
In the 19th and 20th centuries, yoga reawakened from relative obscurity and stepped into the global spotlight—thanks to visionary teachers who bridged the gap between ancient wisdom and modern life.
The Western Influence
As colonial and scientific ideologies swept through India, Western-educated Indian reformers sought to reclaim and rationalise their spiritual heritage. They stripped away superstition and focused on yoga’s core philosophical and scientific underpinnings.
This era saw yoga reborn as a "spiritual science"—a blend of metaphysical insight and practical self-mastery.
The Revivalists: Vivekananda, Sivananda, and Shri Yogendra
Swami Vivekananda
At the 1893 World Parliament of Religions in Chicago, Swami Vivekananda stunned the West with his eloquent exposition of Vedanta and Raja Yoga. His charisma and clarity lit the fuse for yoga’s international journey.
Shri Yogendra
Known as the Father of the Modern Yoga Renaissance, Shri Yogendra founded The Yoga Institute in 1918. He combined traditional hatha yoga with Western physical culture, pioneering an accessible, health-focused form of yoga still practiced today.
Swami Sivananda
A former doctor turned sage, Swami Sivananda founded the Divine Life Society in Rishikesh. Author of over 200 books, he made yoga widely available to householders, emphasising health, service, and spiritual growth.
His disciples spread his message far and wide:
Swami Vishnudevananda founded Sivananda Yoga Vedanta Centres globally.
Swami Satyananda created the Bihar School of Yoga and introduced systematic yoga education.
Swami Satchidananda opened Woodstock in 1969 and helped establish the Yoga Alliance.
Swami Chinmayananda launched the Chinmaya Mission, merging yoga with Vedantic wisdom.
The Global Explosion: Yoga in the West (Mid-20th Century–Present)
As the 20th century progressed, yoga evolved from a spiritual practice to a global wellness lifestyle. Asana took centre stage, popularised by influential teachers like:
T. Krishnamacharya, who developed vinyasa flow and mentored legends like Pattabhi Jois (Ashtanga), B.K.S. Iyengar (Iyengar Yoga), and Indra Devi.
Desikachar and G. Mohan, who adapted yoga therapeutically for modern needs.
In the 21st century, yoga has become a household word—offered in gyms, taught online, and prescribed for everything from anxiety to arthritis.
