In Holy Science book, based on my limited knowledge on Sanskrit, the English translation (not the commentary) seems a bit off from the original in few places. e.g., Ch1 Sutra 15/16. Wondering who wrote the translation? Was it done during Sri Paramhansa Yogananda's time? or later? Are there any alternative translations or detailed commentary available for this concise but intense book?

A publisher’s note indicates that the English translation of the slokas which appear at the beginning of each section were translated by the publisher (Self-Realization Fellowship).
From my knowledge and after some inquiries by me regarding the question, it appears that the book was written by the author in English. There was a French-language edition (never published I believe) and it appeared in serial form before its publication in English in 1920 or 1922, approx.
If you would like to address this may I suggest you write to Self-Realization Fellowship (www.yogananda-srf.org) in Los Angeles, California.
