jnanam te ‘ham sa-vijnanam
idam vaksyamy asesatah
yaj jnatva neha bhuyo nyaj
(Knowledge of the Absolute, Text 2 Chapter 7)
I shall now declare unto you in full this knowledge, both phenomenal and numinous. This being known, nothing further shall remain for you to know.
*** One should be intelligent enough to know the source of all knowledge, who is the cause of all causes and the only object for meditation in all types of yoga practice. When the cause of all causes becomes known, then everything knowable becomes known, and nothing remains unknown.
