The Upanishads - Mandhata Global

Heaven (i.e. Brahman, dwelling in the heart).
4
"Now, this serene being, after rising from this physical
body and attaining the Highest Light, reaches his own
true form. This is the Self." Thus he (i.e. the teacher,
questioned by his pupils) spoke. Continuing, he said:
"This is the immortal, the fearless. This is Brahman.
And of this Brahman the name is Satyam, the True."
5
This name Satyam consists of three syllables: Sat, ti
and yam. That which is Sat signifies the Immortal; and
that which is ti is the mortal; and yam binds them both.
Because this syllable binds both, therefore it is called
yam. He who knows this goes every day in deep sleep
to Heaven (i.e. Brahman, dwelling in the heart).
