। । ॥ ८१७ ॥
In plain words
To gain firm conviction in the truth of the Self, reflect upon it again and again. Until every false notion regarding who you are is utterly destroyed in the mind, uninterrupted meditation must be practiced by one who longs for freedom.
Close to the Sanskrit
For the certainty of the true nature of the Self, reflection must be done repeatedly. As long as the inverted notion of the Self does not perish in the mind, so long uninterrupted meditation must be done by one desiring liberation.
