PURPORT

Brhaspati, the spiritual master of the demigods, informed Indra, "Ordinarily, Bali and his forces could not achieve such strength, but it appears that the brahmana descendants of Bhrgu Muni, being pleased with Bali Maharaja, endowed them with this spiritual power." In other words, Brhaspati informed Indra that Bali Maharaja's prowess was not his own but that of his exalted guru, Sukracarya. We sing in our daily prayers, yasya prasadad bhagavat-prasado yasyaprasadan na gatih kuto 'pi. By the pleasure of the spiritual master, one can get extraordinary power, especially in spiritual advancement. The blessings of the spiritual master are more powerful than one's personal endeavor for such advancement. Narottama dasa Thakura therefore says:

guru-mukha-padma-vakya, cittete kariya aikya,
ara na kariha mane asa

Especially for spiritual advancement, one should carry out the bona fide order of the spiritual master. By the parampara system, one can thus be endowed with the original spiritual power coming from the Supreme Personality of Godhead (evam parampara-praptam imam rajarsayo viduh).
