But all these true desires are under a false cover. Though they rest on the Self, they are all false. This is why if a relative dies, one does not see him again in this world.
Further, those of his relatives who are still alive and those who are dead, and also those things a person cannot get even if he wishes for them—all these he gets by going within his heart. All true desires of a person are in his heart, though they are hidden. It is like when there is gold hidden someplace underground and people who are ignorant of it walk over that spot again and again, knowing nothing about it. Similarly, all these beings go to Brahmaloka every day, and yet they know nothing about it because they are covered by ignorance.
The Self resides in the heart. The word hṛdayam is derived thus: hṛdi + ayam—‘it is in the heart.’ Therefore, the heart is called hṛdayam. One who knows thus goes daily to the higher world (i.e., in his dreamless sleep he is one with Brahman).
The teacher said - ‘Then, this person, who is the embodiment of happiness, emerging from the body and attaining the highest light, assumes his real nature. This is the Self. It is immortal and also fearless. It is Brahman. Another name for Brahman is satya, Truth.’
Sa, tī, and yam—these are the three syllables (which represent Brahman). Sa stands for that which is immortal. Ti stands for that which is mortal. And yam stands for that which controls both the mortal and the immortal. As both (the mortal and the immortal) are controlled by it, it is called yam. The person who knows the significance of these three syllables enjoys divine bliss every day in dreamless sleep.
