jñānavijñānatṛptātmā kūṭastho vijitendriyaḥ . yukta ityucyate yogī samaloṣṭāśmakāñcanaḥ
心靈滿足於知識與實證者，不動搖，感官受控者，被稱為與「真我」（Atman）合一。這樣的瑜伽士，視泥塊、石頭與黃金為等同。
One whose mind is satisfied with knowledge and realization, who is unmoved, who has his organs under control, is sadi to be Self-absorbed. The yogi treats eally a lump of earth, a stone and gold.
「知識」（Jnana）是指透過研讀經典而獲得的理論知識。「實證」（Vijnana）則是透過「真我」實證（Anubhava，靈性體驗）而獲得的直接知識。「不動搖」（Kutastha）意指如鐵砧般不變。各種鐵塊在鐵砧上被錘打成形，但鐵砧本身保持不變。同樣地，瑜伽士雖與感官對象接觸，卻保持不動搖、不改變、不受影響。因此他被稱為「不動搖者」（Kutastha）。「不動搖者」（Kutastha）也是「梵」（Brahman）的別名，是心靈的寂靜見證者。
Jnana is ParokshaJnana or theoretical knowledge from the study of the scriptures. Vijnana is Visesha Jnana or Aparoksha Jnana? i.e.? direct knowledge of the Self through Selfrealisation (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 senseobjects. So he is called Kutastha. Kutastha is another name of Brahman? the silent witness of the mind. (Cf.V.18VI.18)
