Aspects of Jnana Sadhana
A Sadhaka should reflect and meditate. Sravana is hearing of Srutis, Manana is thinking and reflecting, Nididhyasana is constant and profound meditation. Then comes Atma-Sakshatkara or direct realisation.
This is also known as Brahmanubhava or Aparokshanubhuti. Then all doubts and delusions melt away. The knot of ignorance (Hridaya Granthi) is cut asunder. All Karmas (Sanchita and Prarabdha) are destroyed. The Jnani attains Sat-Chit-Ananda state. He is freed from the wheel of Samsara, from births and deaths with its concomitant evils.
The student in the path of Jnana Yoga repeats Om or Soham or Sivoham or Aham Brahma Asmi or Om Tat Sat and associates the ideas of Purity, Perfection, Infinity, Eternity, Immortality, Sat-Chit-Ananda along with the repetition of the above formulae.
