The Yogi who is satisfied with the knowledge and the wisdom (of the Self), who has conquered the senses, and to whom a cod of earth, a piece of stone and a piece of gold are the same, is said to be harmonised (i.e., is said to have attained Nirvikalpa samadhi).
Commentary: Jnana is Paroksha-Jnana or theoretical knowledge from the study of the scriptures. Vijnana is Visesha Jnana or Aparoksha Jnana, i.e., direct knowledge of the Self through Self-realisation (spiritual experience or Anubhava).
Kutastha means changeless like the anvil. Various kinds of iron pieces are hammered and shaped on the anvil, but the anvil remains unchanged. Even so the Yogi remains unshaken or unchanged or unaffected though he comes in contact with the sense-objects. So he is called Kutastha. Kutastha is another name of Brahman , the silent witness of the mind. (Cf.V.18; VI.18)
