This is the most difficult path, requiring tremendous strength of will and intellect. Taking the philosophy of Vedanta the Jnana Yogi uses his mind to inquire into its own nature. We perceive the space inside and outside a glass as different, just as we see ourselves as separate from God. Jnana Yoga leads the devotee to experience his unity with God directly by breaking the glass, dissolving the veils of ignorance. Before practicing Jnana Yoga, the aspirant needs to have integrated the lessons of the other yogic paths - for without selflessness and love of God, strength of body and mind, the search for self-realization can become mere idle speculation.
