Isn’t sleeping with Vrinda by Vishnu an act of injustice?

Let’s see what veda say about Sriman Narayana:

Salutations again and again to the one with forms everywhere, the truthful one, the supreme Brahman, the highest Being, the one who is dark and yellow in hue, the one who is fully celibate, and the all seeing one whose form is the universe.

Sriman Narayana is considered to be SUPREME YOGI. He is considered to be eternally celibate.

Now people might ask, “How could he have children if he was eternally celibate?”. Always remember, Lord Brahma was born from the navel of Sri Hari without help of Mata Lakshmi. He had children in his avatar from his Yogic ability.

One thing should be clearly understood, to marry Sri Narayana or Mahadeva or Sri Rama or Sri Krsna is not a piece of cake. The person should undergo severe austerities and penance to get him as husband, so did Tulsi. Also it should be clear that Sriman Narayana marries no one except Mata Lakshmi :

Devi Puraana, Book 9, Chapter 24

O Honoured One! For a long time you performed tapasyâ in this Bhârata, to get Me. S’ankhachûda, too, performed tapasyâ for a long time to get you. By that tapas, S’ankhachûda got you as wife. Now it is highly incumbent to award you also with the fruit that you asked for. Therefore I have done this.

Now quit your this terestrial body and assume a Divine Body and marry Me. O Râme! Be like Laksmî. This body of yours will be known by the name of Gandakî, a very virtuous, pure and pellucid stream in this holy land of Bhârata. Your hairs will be turned into sacred trees and since they are born of Tulasi's hair they will be called Tulasi.

 Tulasi devi is considered to be portion of Mahalakshmi Devi herself according to Devi Bhagvat who got cursed and got married to Sankhachuda, who too did austerities to get her as wife:

“Then, on an auspicious day, on an auspicious moment, auspicious Yoga, auspicious Lagna, auspicious Amsa, and on auspicious combination of planetary rulers and their houses, she delivered on the full moon night of the month of Kârtik one beautiful daughter, the incarnation of Laksmî. The holy wise men named Her Tulasî.”

Please remember a thing, Sriman Narayan’s body is not material. It is completely spiritual. So we too should percieve his leelas through spiritual point of view!

OM NAMO NARAYANA!
