Karma yoga is one of the four classical schools of yoga alongside Jnana (knowledge or self-study), Bhakti (devotion) and Raja (meditation), each offering a path to moksha (spiritual liberation) and self-realization.
Derived from the Sanskrit term for “action”, karma is action, work, or deed, and its effect or consequences. In yoga, karma is known as the path of action, or selfless service towards others.
Karma yoga is considered to be one of the most practical and effective means of spiritual development.
