bhaktyā bhaktena nirguṇaḥ
prahrādaṁ praṇataṁ prīto
The word nirguṇa is important. The Māyāvādī philosophers accept the Absolute Truth as nirguṇa or nirākāra. The word nirguṇa refers to one who possesses no material qualities. The Lord, being full of spiritual qualities, gave up all His anger and spoke to Prahlāda.
