Acharya Prashant explains that the best spiritual knowledge is like the wood used in a funeral pyre. This wood burns down the dead body, which represents all that is dead, unnecessary, and decomposing within a person. After performing this function, the wood itself disappears. Similarly, the best knowledge removes one's falseness and then sublimates, leaving the mind totally free from both worldly and spiritual knowledge. The speaker then categorizes people based on their relationship with knowledge. The first kind consists of those who carry a lot of worldly knowledge from fields like science and economics, firmly believing it can redeem them. They trust their intellect but continue to suffer. The second category includes those who, dissatisfied with worldly knowledge, turn to spirituality and accumulate a great deal of it. These individuals suffer doubly, as they are now burdened by two kinds of knowledge, and their expectations from both are belied. Most people who dabble in spirituality fall into this group, and their misery is compounded. A third type of person sees the inadequacy of worldly knowledge and withdraws trust from it, only to place that trust in spiritual knowledge and the scriptures. They become empty of the world but full of scriptures, which then become an alternate, make-believe world of illusion for them. This state is considered even worse. The fourth type, which the speaker says Ashtavakra refers to, is the mind that frees itself even from spiritual knowledge and the scriptures. This mind becomes totally light and empty. This fourth person is the free man, and their state is liberation. They do not even meditate or engage in any spiritual practice, having left yoga far behind. They live fearlessly, without the support of any mental projections. This freedom comes from realizing that what is sought through knowledge is one's own basic reality, already present within. This is faith: not relying on knowledge or any mental prop, but having central trust in the Absolute, which is one's own heart.
