8.11 Pravaksye, I shall speak; te, to you; samgrahena, briefly; tat, of that; which is called the aksaram, immutable-that whch does not get exhausted, which is indestructible; padam, Goal to be reached; yat, which; veda-vidah, the knowers of the Vedas, the knowers of the purport of the Vedas; vedanti, declare, speak of It as opposed to all alifications-'It is neither gross nor minute' (Br. 3.8.8) etc.-, in accordance with the Upanisadic text, 'O Gargi, the knowers of Brahman say this Immutable (Brahman) is that' (ibid); and further, yat, into which, after the attainment of complete realization; visanti, enter; yatayah, the diligent ones, the monks; who have become vita-ragah, free from attachment; and icchantah, aspiring to know (-to know being supplied to complete the sense-); yat, which Immutable; people caranti, practise; brahmacaryam, celibacy-at the teacher's house.
