Whom does the Upanishad call _The chief among the knowers of Brahma?_ [Footnote: Brahmavidāmvaristhah.] He is defined as _He whose joy is in Brahma, whose play is in Brahma, the active one._ [Footnote: Ātmakrīrha ātmaratih kriyāvān.] Joy without the play of joy is no joy at all--play without activity is no play. Activity is the play of joy. He whose joy is in Brahma, how can he live in inaction? For must he not by his activity provide that in which the joy of Brahma is to take form and manifest itself? That is why he who knows Brahma, who has his joy in Brahma, must also have all his activity in Brahma--his eating and drinking, his earning of livelihood and his beneficence. Just as the joy of the poet in his poem, of the artist in his art, of the brave man in the output of his courage, of the wise man in his discernment of truths, ever seeks expression in their several activities, so the joy of the knower of Brahma, in the whole of his everyday work, little and big, in truth, in beauty, in orderliness and in beneficence, seeks to give expression to the infinite. Brahma himself gives expression to his joy in just the same way. _By his many-sided activity, which radiates in all directions, does he fulfil the inherent want of his different creatures._ [Footnote: Bahudhā çakti yogāt varņānanekān nihitārtho dadhāti.] That inherent want is he himself, and so he is in so many ways, in so many forms, giving himself. He works, for without working how could he give himself. His joy is ever dedicating itself in the dedication which is his creation.
