Jnana Yoga is the process of converting intellectual knowledge into practical wisdom. It is a discovery of human dharma in relation to nature and the universe. Jnana Yoga is described by tradition as a means to obtain the highest meditative state and inner knowledge.
Jnana literally means ‘knowledge’, but in the context of yoga it means the process of meditative awareness which leads to illuminative wisdom. It is not a method by which we try to find rational answers to eternal questions, rather it is a part of meditation leading to self-enquiry and self-realisation.
Some of the components of Jnana Yoga are: (1) not believing but realising, (2) self-awareness leading to self-analysis, (3) experiencing knowledge, (4) realising the personal nature, (5) developing intuitive wisdom, (6) experiencing inner unity.
Classical books on this subject are Yoga Darshan, Yoga Sadhana Panorama series, Nine Principal Upanishads and others.
