9.6.51

ekaścaran rahasi cittamananta īśe % yuñjīta tadvratiṣu sādhuṣu cet prasaṅgaḥ //

Wandering alone in solitude, one should fix the mind on the infinite Lord; / if there must be association, it should be with saintly devotees devoted to Him.

9.6.51.p2

ekastapasvyahamathāmbhasi matsyasaṅgāt $ pañcāśadāsamuta pañcasahasrasargaḥ &

I was a solitary ascetic in the water; then, through attachment to a fish, / I became fifty, and then produced five thousand offspring.

52. I was alone, engaged in tapas; but by association with the fish under water, I became fifty as it were with fifty wives, and five thousand with five thousand sons; I do not see the end of my wishes relating to this and that world, as my judgment is lost under the force of the gunas of Maya and I am made to think that the gross objects are the (great) things to be attained.

9.6.51.p3

ekastapasvyahamathāmbhasi matsyasaṅgāt $ pañcāśadāsamuta pañcasahasrasargaḥ &

I was a solitary ascetic in the water; then, through attachment to a fish, / I became fifty, and then produced five thousand offspring.
