Here in this verse the word purusam is very significant. The Lord is never female. He is always male (purusa). Therefore the impersonalist who imagines the Lords form as that of a woman is mistaken. The Lord appears in female form if necessary, but His perpetual form is purusa because He is originally male. The feminine feature of the Lord is displayed by goddesses of fortuneLaksmi, Radharani, Sita, etc. All these goddesses of fortune are servitors of the Lord; they are not the Supreme, as falsely imagined by the impersonalist. Lord Krsna in His Narayana feature is always four handed. On the Battlefield of Kuruksetra, when Arjuna wanted to see His universal form, He showed this feature of four-handed Narayana. Some devotees are of the opinion that Krsna is an incarnation of Narayana, but the Bhagavata school says that Narayana is a manifestation of Krsna.
