The Secret of Transcendental Knowledge
Introduction by Śrīla Baladeva Vidyābhūṣaṇa
Now it will be said that transcendental knowledge is a great secret. In
Śvetāśvatara Upaniṣad (6.22) it is said:
vedānte paramaṁ guhyaṁ
purā-kalpe pracoditam
nāpraśāntāya dātavyaṁ
nāputrāyāśiṣyāya vā
"This, the supreme secret of Vedic literature, should not be spoken to one who
is not peaceful or in control of his senses, nor to one who is not a dutiful son or an
obedient disciple."
Saṁśaya (doubt): Should transcendental knowledge be taught to everyone or
should it not?
Pūrvapakṣa (the opponent speaks): Out of compassion the teacher does not
distinguish between who is fit and who is not fit to receive transcendental
knowledge. He reveals the truth to all.
Siddhānta (conclusion): In the following words the author of the sūtras gives
His conclusion.
