18.12 These trividham, threefold-of three kinds; phalam, results; karmanah, of actions characterized as the righteous and the unritheous; anistam, the undesirable, consisting in (birth in) hell, (among) animals, etc.; istam, the desirable, consisting in (birth as) gods and others; and misram, the mixed, having a mixture of the desirable and the undesirable, consisting in (birht as) human beings;-these results that are of these kinds, bhavati, accrues; pretya, after death, after the fall of the body; atyaginam, to those who do not resort to renunciation, to the unilllumined, the men with rites and duties, who are not men of renunciation in the truest sense.

Tu, but; na kvacit, never; sannyasinam, to those who resort tomonasticism for the sake of the highest Reality, to the class of monks called paramahamsas who remain steadfast in Knowledge alone.
