Mbh 6.33.2b

Always glorifying me, (or) striving with firm vows, (or) bowing down to me, with reverence and ever devoted, (they) worship me.[223] Others again, performing the sacrifice of knowledge, worship me, (some) as one, (some) as distinct, (some) as pervading the universe, in many forms.[224] I am the Vedic sacrifice, I am the sacrifice enjoined in the Smritis, I am Swadha, I am the medicament produced from herbs; I am the mantra, I am the sacrificial libation, I am the fire, and I am the (sacrificial) offering.[225] I am the father of this universe, the mother, the creator, grandsire; (I am) the thing to be known, the means by which everything is cleaned, the syllable Om, the Rik, the Saman and the Yajus, (I am) the goal, the supporter, the lord, the on-looker, the abode, the refuge, the friend, the source, the destruction, the support, the receptacle, and the undestructible seed. I give heat, I produce and suspend rain; I am immortality, and also death; and I am the existent and the non-existent, O Arjuna. They who know the three branches of knowledge, also drink the Soma juice, and whose sins have been cleansed worshipping me by sacrifices, seek admission into heaven; and these attaining to the sacred region of the chief of the gods, enjoy in heaven the celestial pleasure of the gods. Having enjoyed that celestial world of vast extent, upon exhaustion of their merit they re-enter the mortal world. It is thus that they who accept the doctrines of the three Vedas and wish for objects of desires, obtain going and coming. Those persons who, thinking (of me) without directing their minds to anything else, worship me, of those who are (thus) always devoted (to me)--I make them gifts and preserve what they have. Even those devotees who, endued with faith, worship other godheads, even they, O son of Kunti, worship me alone, (though) irregularly.[226] I am the enjoyer, as also the lord, of all sacrifices. They, however, do not know me truly; hence they fall off (from heaven).
