saḥ aham - I; kāla-avaśeṣeṇa - with whatever time remains; śoṣayiṣye - shall reduce to the minimum; aṅgam - this body; ātmanaḥ - my; apramattaḥ - unbewildered; akhila - entire; sva-arthe - in the real self-interest; yadi - if; syāt - there remains any (time); siddhaḥ - satisfied; ātmani - within myself.

If there is any time remaining in my life, I will perform austerities and force my body to subsist on the bare necessities. Without further confusion I shall pursue that which constitutes my entire self-interest in life, and I shall remain satisfied within the self.
