English Commentary By Swami Sivananda

15.4 ततः then, पदम् goal, तत् That, परिमार्गितव्यम् should be sought for, यस्मिन् whither, गताः gone, न not, निवर्तन्ति return, भूयः again, तम् that, एव even, च and, आद्यम् primeval, पुरुषम् Purusha, प्रपद्ये I seek refuge, यतः whence, प्रवृत्तिः activity or energy, प्रसृता streamed forth, पुराणी ancient.

Commentary:
That which fills the whole world with the form of ExistenceKnowledgeBliss is Purusha. Or, that which sleeps in this Puri (city) of the body is the Purusha.Singleminded devotion which consists of ceaselessly thinking of or meditating on the Supreme Being is the sure means of attaining Selfrealisation. Taking sole refuge in the Primeval Purusha is the means to know or realise that supreme goal goind whither the wise do not return again to this world of death.The aspirant should know the abode of Vishnu. He should struggle hard to reach it. He should seek it by taking refuge in the Primeval Purusha. If he reaches this immortal abode of Vishnu or the imperishable Brahmic seat of ineffable splendour and glory he will never return to this mortal world.The Primeval Purusha or the pure, Supreme Being Who is ExistenceKnowledgeBliss Absolute is the goal or the supreme abode or the abode of Vishnu. Just as illusory objects like elephants, horses, etc., come forth through the jugglery of the magician, so also this ancient energy or the original divine power or emanation of this tree or illusory Samsara has streamed forth from that Primeval Purusha.What sort of persons reach that goal eternal Listen.

English Translation Of Sri Shankaracharya's Sanskrit Commentary By Swami Gambirananda

15.4 Tatah, thereafter; tat, that; padam, State of Visnu; parimargitavyam, has to be sought for, i.e. realized; gatah, going, entering; yasmin, where, into which State; they na, do not; nivartanti, return; bhuyah, again, for worldly life. As to how It is to be sought for, the Lord says: Prapadye, I take refuge; tam, in that; adyam, Primeval-existing from the beginning; purusam, Person, who has been mentioned by the word State; eva, Himself. The search has to be carried on thus, i.e., by taking refuge in Him. Who is that Person? That is being stated: Yatah, from whom, from which Person; prasrta, has ensued, like jugglery from a magician; purani, the eternal; pravrttih, Manifestation, the magic Tree of the World. What kind of persons reach that State? This is being answered:

English Translation By Swami Gambirananda

15.4 Thereafter, that State has to be sought for, going where they do not return again: I take refuge in that Primeval Person Himself, from whom has ensued the eternal Manifestation.
