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)

# BG 6.8
The person of self-restraint who continuously contemplates upon the atman—the Self known through the teachings of scripture—swiftly attains divine contentment and bliss, becoming thereby a perfected yogi. His satisfaction springs not from scholarly mastery of the scriptures, but from direct divine experience of the atman, which far transcends the mere satisfaction of scriptural study.
According to Sri Shankaracharya, knowledge means understanding the truths expounded in scripture, while wisdom means the direct experiential realization of those truths known through scripture. When both knowledge and wisdom are attained, the heart of the person experiences supernatural contentment.
In Vedanta, the atman is called kutastha—immovable and unchanging. Kuta means anvil. The blacksmith places a heated piece of iron upon the anvil and strikes it with a hammer, shaping the iron into various forms. The hammer's blows affect the iron, yet the anvil itself remains unmoved. It remains steadfast and unaltered while serving as the foundation for the iron's transformation. Thus kutastha means that which, like the anvil, remains immovable and unmodified.
The person satisfied through knowledge and wisdom, having realized the kutastha atman, becomes himself kutastha in all circumstances. He becomes the witness of all, seeing equally. For him, clay, stone, and gold are all the same—he maintains equal regard toward all things. Ordinary people, driven by attachment and aversion, experience joy or sorrow through the gain or loss of what they desire or dislike. The measure of true knowledge is this: when such objects are obtained, the person remains unmoved and equal.
In a dream, a person may accumulate great wealth or lose all possessions, yet upon waking, the gain or loss experienced in the dream holds no meaning. Similarly, for the person established in the supreme, infinite Self—beyond the limitations imposed by the body and mind—clay, stone, and gold hold no significance. They can neither increase nor diminish his bliss. He becomes the sole master of supreme joy. Even Kubera, the treasurer of heaven, would not be moved to exultation by the kingdom of the earth, for it adds nothing to his wealth.
