In plain words
The quarter that is left we use for our own selfish ends, and we forget to think of the good of others. So the young must be fully ready to set this body to karmas done for the good of others, to believe them to be service of the Paramātma, and so to make our lives worthwhile. At this age we must keep ourselves ready to serve others, and not be ready to have others serve us. This is sloth. To serve others is the Soham principle. So you who are young, push sloth aside to some extent, develop faith in God to some extent, believe to some extent in the principle of the Lord of all in all beings, and, to make your service worthwhile, try to understand the sacred histories. Our history does hold many inner meanings for this. For this we must also make efforts of certain kinds. A small example. By Īśvara we mean one who wears the matted locks, holds the trident, bears the three eyes, is wrapped in an elephant's hide and then smeared with vibhūti, and is there in many forms: in the way of this world, that is one kind of experience. When we wish to describe this very thing beautifully:
With the digit of the crescent moon shining on the crown, with a thick cluster of matted locks in their beauty, with the gleam of the sky's river running through those locks, with the glorious eye upon the brow, with a throat as dark as the dark nēreḍu fruit, with the serpent bangle on the hand, with the elephant's hide wound about the waist, with the holy ash that glows over the whole body, with the broad kuṅkuma mark drawn upon the forehead, with lips red from tāmbūla, grown lovely in the six śāstras, laughing at the dark lilies and plundering their beauty, with a body of gleaming dusky hue, He who dwells in Parti has appeared in person today.
