Vidyaranya Swami (1296-1386), author of the wonderful Advaita Vedanta text Panchadasi and Shankaracharya (head monk) of Sringeri Math, wrote another less well known text called Jivanmukti Viveka. In it he, in some considerable detail, outlines the path to Jivanmukti, or liberation in this life.
In Chapter 2 Vidyaranya repeatedly makes the point that liberation or jnana cannot occur without both manonasa (destruction of the mind) and vasana kshaya (destruction of the habitual tendencies). To support this view he quotes from the Amritabindu Upanishad, verses 2-5, as follows:
Mind alone is the cause of bondage or liberation; lost in enjoyment it leads to bondage, emptied of the objective it leads to liberation.
As mind emptied of the objective leads to liberation, one desirous of liberation must always try to wipe off the objective from the plane of his mind.
The mind severed from all connection with sensual objects, and prevented from functioning out, awakes into the light of the heart, and finds the highest condition.
The mind should be prevented from functioning, until it dissolves itself in the heart. This is Jnana, this is Dhyana, the rest is all mere concoction of untruth.
Jnana refers to liberation, and dhyana means meditation, stating this instruction refers to the means (meditation) and the fruit (liberation). The last line can alternatively be rendered as ‘…all else is mere argumentation and verbiage’.
