Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 19-20


स विलोक्येन्द्रवाय्वादीन् नि:सत्त्वान्विगतप्रभान् ।लोकानमङ्गलप्रायानसुरानयथा विभु: ॥ १९ ॥समाहितेन मनसा संस्मरन्पुरुषं परम् ।उवाचोत्फुल्ल‍वदनो देवान्स भगवान्पर: ॥ २० ॥


sa vilokyendra-vāyv-ādīnniḥsattvān vigata-prabhānlokān amaṅgala-prāyānasurān ayathā vibhuḥ


Upon seeing that the demigods were bereft of all influence and strength and that the three worlds were consequently devoid of auspiciousness, and upon seeing that the demigods were in an awkward position whereas all the demons were flourishing, Lord Brahmā, who is above all the demigods and who is most powerful, concentrated his mind on the Supreme Personality of Godhead. Thus being encouraged, he became bright-faced and spoke to the demigods as follows.


After hearing from the demigods the real situation, Lord Brahmā was very much concerned because the demons were unnecessarily so powerful. When demons become powerful, the entire world is placed in an awkward position because demons are simply interested in their own sense gratification and not in the welfare of the world. Demigods or devotees, however, are concerned with the welfare of all living beings. Śrīla Rūpa Gosvāmī, for example, left his ministership and went to Vṛndāvana for the benefit of the entire world (lokānāṁ hita-kāriṇau). This is the nature of a saintly person or demigod. Even impersonalists think of the welfare of all people. Thus Brahmā was very much concerned at seeing the demons in power.
