गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

Sūtra 1
āvṛttir asakṛd upadeśāt
āvṛttiḥ—repetition; asakṛt—many times; upadeśāt—because of the teaching.
It is repeated many times, for that is the teaching.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
The various activities of devotional service, which begin with hearing the
glories of the Lord, should be repeated many times. Why is that? The sūtra
explains, "asakṛt" (many times, for that is the teaching). In the Chāndogya
Upaniṣad (6.8.7) it is said:
sa ya eṣo 'ṇimā. etad ātmyam idaṁ sarvam. tat satyam. sa ātmā. tat tvam asi.
"He is the resting place. Everything comes from Him. He is the supreme reality.
He is the supreme person. You are like unto Him."
In these words Śvetaketu was instructed nine times. It is illogical to say that if
the scripture mentions an activity once then there is no need to perform that
activity many times. This may apply to an activity where the result is not directly
seen, but for an activity that has the direct perception of the Supreme Personality
of Godhead as its result, a result that is clearly seen, the activity must be repeated
until the result is obtained. This is like threshing rice, where the activity must be
continued until the husk is removed. Therefore the devotional activities that begin
with hearing the Lord's glories should be performed again and again until the
result is obtained.
Sūtra 2
liṅgāc ca
liṅgāt—because of a sign; ca—also.
Also because of a sign.
