वेदान्त पारिजात सौरभ (भगवद् निम्बार्काचार्य - द्वैताद्वैत वेदान्त ब्रह्मसूत्र भाष्य सटीक)

[SŪ. 3. 4. 50 VEDĀNTA-KAUSTUBHA 775
ADH. 14.]
Baladeva
He, like Nimbārka, takes this sūtra (sūtra 50 in his commentary)
as forming an adhikaraṇa by itself, but dealing with an entirely
different topic, viz. the keeping of knowledge as secret. Hence the
sūtra: "(Let one remain) without manifesting (i.e. revealing the
knowledge attained), on account of connection (i.e. tradition)".
That is, when a preceptor teaches his disciple, he should ask the
disciple to keep what he has learnt a strict secret, for such is the
tradition ¹.
Adhikaraṇa 14: The section entitled "In this
life" (Sūtra 50)
SŪTRA 50
"(THERE IS THE RISE OF KNOWLEDGE) IN THIS LIFE IF OBSTRUC-
TION BE NOT PRESENT, ON ACCOUNT OF THAT BEING SEEN."
Vedānta-pārijāta-saurabha
"If obstruction" be non-existent, then there is rise of knowledge
"in this life"; if it be present, in the next, "on account of that being
declared" by the text: "Then Naciketas, having obtained the know-
ledge declared by Death" (Kaṭha 6.18 ²) and so on
Vedānta-kaustubha
Having stated the multitude of means that lead to the rise of
knowledge, the author is now considering its time.
On the doubt, viz. whether through the means, demonstrated
in the group of aphorisms ending with "Non-manifesting, on
account of connection" (Br. Sū. 3.4.49), knowledge arises in this
life or in the next,—the prima facie view is that in accordance with
the scriptural text: "Let one desirous of salvation perform sacrifices"
(Tait. Saṁ. 2.5.5 ³) and so on, people strive for only prosperity
