In plain words
We use it for useless work. Truly, because today we are people who do not know the worth of humanness, we go on leading our life in this way, to no purpose. ‘Somehow we have got this human birth; this body came to us naturally, with nature; so let us eat and drink with this body, go about in luxury as we please, pass our life somehow happily and then close our eyes’: with this we live heedlessly. This is not the right mark of humanness. Jantūnāṃ narajanma durlabhaṃ. How sacred is the fruit by which this sacred human birth comes to us! We must never at all consent to waste this sacred birth without understanding it, merely like beasts, birds and wild animals. So, when we recognise the truth that the divine Ātma moves in each and every person as the ground of all and as the one form, we come to experience, in some measure, the worth of human birth and the heedlessness of this Ajñāna, and it gives us some zeal to enter the divine path. To decide ‘This is so’ or to settle ‘This is not so’: these are the very marks of Dvaita; in Advaita such things can find no place at all.
They can say, ‘This is not it,’ but to say, ‘This is Brahman,’ is beyond their power. Eternal and Satya, infinite, Jñāna, the one alone: that itself is Brahman, and words cannot reach it.
So they said. Today we must try to recognise the truth that Brahman alone, the one, shines in every form as the one Ātma. Only when we recognise that truth can we attain the state of Viṣṇu as well. So, in this śloka of the Bhaja Govindam, which says that if this state of Viṣṇu is to come to us we must understand equanimity, Śaṅkara Bhagavatpāda gave the world a fine example.
