SB 8.20.14
sri-suka uvaca
evam asraddhitam sisyam
anadesakaram guruh
sasapa daiva-prahitah
satya-sandham manasvinam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami continued: Thereafter, the spiritual master, Sukracarya, being inspired by the Supreme Lord, cursed his exalted disciple Bali Maharaja, who was so magnanimous and fixed in truthfulness that instead of respecting his spiritual master’s instructions, he wanted to disobey his order.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The difference between the behavior of Bali Maharaja and that of his spiritual master, Sukracarya, was that Bali Maharaja had already developed love of Godhead, whereas Sukracarya, being merely a priest of routine rituals, had not. Thus Sukracarya was never inspired by the Supreme Personality of Godhead to develop in devotional service. As stated by the Lord Himself in Bhagavad-gita (10.10):
tesam satata-yuktanam
bhajatam priti-purvakam
dadami buddhi-yogam tam
yena mam upayanti te
“To those who are constantly devoted and worship Me with love, I give the understanding by which they can come to Me.”
Devotees who actually engage in devotional service with faith and love are inspired by the Supreme Personality of Godhead. Vaisnavas are never concerned with ritualistic smarta-brahmanas. Srila Sanatana Gosvami has therefore compiled Hari-bhakti-vilasa to guide the Vaisnavas, who never follow the smarta-vidhi. Although the Supreme Lord is situated in the core of everyone’s heart, unless one is a Vaisnava, unless one is engaged in devotional service, one does not get sound advice by which to return home, back to Godhead. Such instructions are meant only for devotees. Therefore in this verse the word daiva-prahitah, “being inspired by the Supreme Lord,” is important. Sukracarya should have encouraged Bali Maharaja to give everything to Lord Visnu. This would have been a sign of love for the Supreme Lord. But he did not do so. On the contrary, he wanted to punish his devoted disciple by cursing him.
