In plain words
Jagadguru Śaṅkara Bhagavatpāda gave many kinds of teachings and established the doctrine of Advaita, and through his disciples he spread abroad many kinds of experiences, the principle of the Ātma, and the special greatness of the Paramātma too; and in all that he spread, he gave this satsaṅga a chief and special place. He taught that satsaṅga itself is the chief, the first step to Mokṣa. Here, when we inquire carefully into the matter called satsaṅga: good companionship, good friendship. But where does the worth of what we call good lie? We must inquire into this matter: what is good? For this, though Śaṅkara gave many kinds of ideals, Vēmana went on handing down the sense of such satsaṅga in a subtle form. As to who the good are, Vēmana taught that whoever conducts himself by these four qualities, ‘by the fire of the belly, by the fire of desire, by the fire of anger, by crookedness’, is a wicked man, and that only the one who lacks these four qualities is a good person. This effort of toiling only for the fire of the belly can in no way be the true fulfilment of being human. Even beasts, birds and wild animals take many pains for the fire of the belly and, following easy ways, are happy. But Vēmana thought it most laughable that, born as men and believing humanness to be near to divinity, even such sacred human beings should make the effort to live merely for the fire of the belly.
Who had food given to the birds of the forest? Who set fodder before the race of beasts? Who had a meal given to the creatures that roam the woods? Who drew water and poured it for the trees?
When the divinity that gives food even to the frog inside the rock is always close at hand, God who gave us birth will not fail to give us food.
