stambhayann ātmanātmānaṁ
yāvat sattvaṁ yathā-śrutam
na śaśāka samādhātuṁ
mano madana-vepitam
stambhayan - trying to control; ātmanā - by the intelligence; ātmānam - the mind; yāvat sattvam - as far as possible for him; yathā-śrutam - by remembering the instruction (of celibacy, brahmacarya, not even to see a woman); na - not; śaśāka - was able; samādhātum - to restrain; manaḥ - the mind; madana-vepitam - agitated by Cupid or lusty desire.
Unless one is very strong in knowledge, patience and proper bodily, mental and intellectual behavior, controlling one’s lusty desires is extremely difficult. Thus after seeing a man embracing a young woman and practically doing everything required for sex life, even a fully qualified brāhmaṇa, as described above, could not control his lusty desires and restrain himself from pursuing them. Because of the force of materialistic life, to maintain self-control is extremely difficult unless one is specifically under the protection of the Supreme Personality of Godhead through devotional service.
