so ’haṁ tathā yatiṣyāmi
yathā na bhūya ātmānam
andhe tamasi majjaye
saḥ—such a person; aham—I; tathā—in that way; yatiṣyāmi—I shall endeavor; yata-citta-indriya—controlling the mind and senses; anilaḥ—and the internal airs; yathā—so that; na—not; bhūyaḥ—again; ātmānam—my soul; andhe—in darkness; tamasi—in ignorance; majjaye—I drown.
I am such a sinful person, but since I have now gotten this opportunity, I must completely control my mind, life and senses and always engage in devotional service so that I may not fall again into the deep darkness and ignorance of material life.
Every one of us should have this determination. We have been elevated to an exalted position by the mercy of Kṛṣṇa and the spiritual master, and if we remember that this is a great opportunity and pray to Kṛṣṇa that we will not fall again, our lives will be successful.
