Vijnana Bhairava Tantra
146: Firm buddhi or intellect without any image or support constitutes meditation. Concentration on an imaginative representation of the divine with a body, eyes, mouth, hands, etc. is not meditation.
147: Worship does not mean offering of flowers, etc. It rather consists in setting one's heart on that highest ether of consciousness which is above all thought-constructs. It really means dissolution of self with perfect ardour (in the Supreme Consciousness known as Bhairava).
148: By being established in even one of the yogas described here, the plenitude of spiritual consciousnesss that goes On developing day after day until it reaches its highest perfection is known here as trpti (satisfaction).
149: When in the fire of Supreme Reality (i. e. Bhairava) in which even the highest void is dissolved, the five elements, the senses, the objects of the senses along with the mind (whose characteristic is dichotomizing thought-constructs) are poured, with consciousness (cetana) as the ladle, then that is real oblation (homa).
150: O Supreme Goddess, Parvati, here the sacrifice characterized by bliss and satisfaction becomes the saviour of all by the destruction of all sins.
