Nandin said: The word Puruṣa is derived thus: puri śete (he who lies in the body). He who worships the deity, the object of worship by means of meditation, is known as yajamāna. Dhyeya (the object of meditation) is the lord himself. Dhyāna is the act of thinking. Niruktī (bliss) the fruit of dhyāna. One who knows about this attains the ultimate reality which is the substratum of Pradhāna and Puruṣa.
