In plain words
In childhood, joining with many others, he becomes one with them in play and song; when youth blossoms, like the god of the flower bow he roams about, infatuated with women; in middle age, sunk in worldly things, he clings to the earning of wealth; when old age comes, not thinking of Murahari, he frets that this is lacking, and that; unable to leave his many evil habits, with no wish to seek the path of Bhakti, he falls into the mire of karma and wanders there: man mixes his birth with the dust.
Embodiments of Prema!
So through all these four stages man keeps changing, and in the end he brings his life to its close. Man's life: like a block of ice, his span of life is melting away. Time is rushing past like a fierce gale. Man leaves the body before he has even recognised his duty. So they have said that such a life is wasted. We must recognise our duty. Only then does one's life bear fruit. We must recognise the truth of why one has come. One has come in order to recognise oneself. All the rest are side matters. So first of all you must find out who you are. At birth we cry, ‘Kohaṃ’, ‘Kohaṃ’, ‘Kohaṃ’.
