Final fight strategy.

DISCIPLE: How long should one continue to enquire into the Self?
MASTER: Non-recrudescence of the darkness of Ignorance is said to be the “limit” of reflection. Therefore one should continue the practice until this darkness of Ignorance does not recur.

DISCIPLE: Can the veiling once removed, return again?
MASTER: Yes. So long as doubts arise, this Ignorance must be inferred to exist.

DISCIPLE: How can there be any doubt left after the Self has been realised?
MASTER: On enquiring into the sheaths and dismissing them as unreal, the Self, their witnessing consciousness is realised to be
unique, finer than ether, even like void. Now that the sheaths have been dismissed as unreal and there is nothing but the void-
like subtle Self, a fear may arise that one is left as nothing or void.

DISCIPLE: How can it be?
MASTER: Transcending all, the Self has nothing in common with worldly things or activities; It transcends the void also;
hence the experience is unique and unearthly. A fear may then arise
“Can this be the Self?
It cannot be
— Should this be the Self, how can I be such a void?”
Even after realising the impartite Self, there is no confidence in one’s own experience; it is regarded as impossible and a great doubt arises. The sense of impossibility gives rise to doubt. But repeated reflection removes
this sense of impossibility. So it is said by Vyasa in the Brahma Sutras:
On account of the repeated instruction
(by the scriptures), (it is) necessary repeatedly (to hear of, reflect and meditate on the Self).

DISCIPLE: What is the “fruit” of such reflection?
MASTER: By continued practice, the veiling is destroyed; with its destruction, the sense of impossibility of the Self shining forth all alone disappears; with its disappearance all obstacles are at an end and then direct experience results as clearly and surely as an apple in the palm of your hand. This is the “fruit”.
