yadṛcchā-lābha-tuṣṭasya - who is satisfied by things obtained by the grace of God; tejaḥ - the brilliant effulgence; viprasya - of a brāhmaṇa; vardhate - increases; tat - that (effulgence); praśāmyati - is diminished; asantoṣāt - because of dissatisfaction; ambhasā - by pouring of water; iva - as; āśuśukṣaṇiḥ - a fire.

A brāhmaṇa who is satisfied with whatever is providentially obtained is increasingly enlightened with spiritual power, but the spiritual potency of a dissatisfied brāhmaṇa decreases, as fire diminishes in potency when water is sprinkled upon it.
