Acharya Prashant explains that people often hide their true, base intentions. For instance, in a UPSC interview, a candidate would not admit they want power to exploit the district, nor would a ministerial candidate admit they seek power so the world will bow to them. He states that wherever there are temptations in your life, that is where your slavery lies. Everyone may not know what to say, but they certainly know what not to say. If the unspeakable is spoken, the relationship breaks. Ironically, the one thing that cannot be said in a relationship is the very thing that should be said. Truth is not dependent on good or bad, or one's likes and dislikes; truth simply is. People get offended by this, claiming that such talk removes love from life, and they get so angry they are ready to attack. The speaker mentions receiving death threats for speaking the truth. Acharya Prashant then refers to the story of Nachiketa from the Kathopanishad, who asked Yama, the god of death, about the nature of the Self (Atma). The first interesting point is about the nature of the Guru. When Nachiketa asks for Self-knowledge (Atma-vidya), Yama, the Guru, does not immediately answer but instead offers worldly pleasures, seemingly refusing the request. This refusal itself is a teaching. The Guru's nature is to give; he cannot withhold knowledge. If a disciple remains deprived, it is their own doing, not the Guru's. The Guru is bound by his nature to give, just as the sun is bound to shine. When Yama says, "I will not tell you," he is, in fact, telling everything. This is unlike worldly people who talk a lot but say nothing of substance. Self-knowledge (Atma-vidya) is the knowledge of the ego (Aham). It is about understanding your own condition. The Upanishads are not about some other world; they are a mirror to your daily life. The one who has mastered their inner world becomes invincible in the outer world. People lose in the world not due to a lack of worldly skills but due to inner deficiencies. One who is not free within lives as a slave outside, constantly justifying their slavery. Quoting Kabir Saheb, he says the worldly person dies a hundred times a day. The one who knows the Self is not someone who has gone to another world, but one who has become the king of this world. The speaker concludes by explaining that spiritual texts are often in complex, coded language because if the truth about people's lives were stated plainly, they would not be able to bear it and would harm the messenger. The coded language ensures that only the worthy and receptive can understand it.
