The Sanskrit word yoga means 'union' or 'yoke' — it refers to the joining of the individual self with the ultimate reality. In Hindu philosophy, yoga is not primarily a physical practice (though hatha yoga, the yoga of physical postures, is one branch of the tradition) but a comprehensive system of spiritual discipline aimed at moksha — liberation from the cycle of birth and death through the direct realization of one's true nature.
The Bhagavad Gita presents four primary paths of yoga, each suited to a different temperament. Jnana yoga is the path of knowledge — the direct inquiry into the nature of the self, culminating in the recognition of Atman as Brahman. Bhakti yoga is the path of devotion — the surrender of the ego to the divine through love, worship, and service. Karma yoga is the path of selfless action — performing one's duty without attachment to results. Raja yoga is the path of meditation — the systematic stilling of the mind through concentration and contemplative practice.
The Yoga Sutras of Patanjali (c. 400 CE) present the most systematic account of raja yoga, describing the eight limbs (ashtanga) of yogic practice: ethical restraints (yama), personal observances (niyama), physical postures (asana), breath control (pranayama), withdrawal of the senses (pratyahara), concentration (dharana), meditation (dhyana), and absorption (samadhi). The goal of all eight limbs is the cessation of the fluctuations of the mind (chitta vritti nirodha) — the state of perfect stillness in which the true nature of the self is revealed.
Frequently Asked Questions
Is yoga just physical exercise?
In the West, yoga is often practiced primarily as physical exercise (hatha yoga). But in the Hindu tradition, yoga is a comprehensive spiritual path — a family of disciplines aimed at the liberation of the self. Physical postures are just one branch of a much larger tree.
What are the four paths of yoga?
The Bhagavad Gita describes four primary paths: jnana yoga (knowledge), bhakti yoga (devotion), karma yoga (selfless action), and raja yoga (meditation). Each path leads to the same goal — moksha — through a different approach suited to different temperaments.
