That of such steady remembrance sacrifices and so on are means will be declared later on (Ve. Sû. III, 4, 26). Although sacrifices and the like are enjoined with a view to the origination of knowledge (in accordance with the passage 'They desire to know,' Bri. Up. IV, 4, 22), it is only knowledge in the form of meditation which--being daily practised, constantly improved by repetition, and continued up to death--is the means of reaching Brahman, and hence all the works connected with the different conditions of life are to be performed throughout life only for the purpose of originating such knowledge. This the Sûtrakâra declares in Ve. Sû. IV, 1, 12; 16; III, 4, 33, and other places. The Vâkyakâra also declares that steady remembrance results only from abstention, and so on; his words being 'This (viz. steady remembrance = meditation) is obtained through abstention (viveka), freeness of mind (vimoka), repetition (abhyâsa), works (kriyâ), virtuous conduct (kalyâna), freedom from dejection (anavasâda), absence of exultation (anuddharsha); according to feasibility and scriptural statement.' The Vâkyakâra also gives definitions of all these terms. Abstention (viveka) means keeping the body clean from all food, impure either owing to species (such as the flesh of certain animals), or abode (such as food belonging to a Kândâla or the like), or accidental cause (such as food into which a hair or the like has fallen). The scriptural passage authorising this point is Ch. Up. VII, 26, 'The food being pure, the mind becomes pure; the mind being pure, there results steady remembrance.' Freeness of mind (vimoka) means absence of attachment to desires. The authoritative passage here is 'Let him meditate with a calm mind' (Ch. Up. III, 14, 1). Repetition means continued practice. For this point the Bhâshya-kâra quotes an authoritative text from Smriti, viz.: 'Having constantly been absorbed in the thought of that being' (sadâ tadbhâvabhâvitah; Bha. Gî. VIII, 6).--By 'works' (kriyâ) is understood the performance, according to one's ability, of the five great sacrifices. The authoritative passages here are 'This person who performs works is the best of those who know Brahman' (Mu. Up. III, 1, 4); and 'Him Brâhmanas seek to know by recitation of the Veda, by sacrifice, by gifts, by penance, by fasting' (Bri. Up. IV, 4, 22).--By virtuous conduct (kalyânâni) are meant truthfulness, honesty, kindness, liberality, gentleness, absence of covetousness. Confirmatory texts are 'By truth he is to be obtained' (Mu. Up. III, 1, 5) and 'to them belongs that pure Brahman-world' (Pr. Up. I, 16).--That lowness of spirit or want of cheerfulness which results from unfavourable conditions of place or time and the remembrance of causes of sorrow, is denoted by the term 'dejection'; the contrary of this is 'freedom from dejection.' The relevant scriptural passage is 'This Self cannot be obtained by one lacking in strength' (Mu. Up. III, 2, 4).--'Exultation' is that
