This is a statement made by Sukadeva Gosvami, who was relating Srimad-Bhagavatam (10.4.46) to Maharaja Pariksit. This quotation concerns the attempted killing of Krsna's sister (Yogamaya), who appeared before Krsna's birth as the daughter of mother Yasoda. This daughter Yogamaya and Krsna were born simultaneously, and Vasudeva replaced Krsna by taking Yogamaya away. When she was brought to Mathura and Kamsa attempted to kill her, Yogamaya slipped out of his hands. She could not be killed. She then informed Kamsa about the birth of his enemy, Krsna, and being thus baffled, Kamsa consulted his associates, who were all demons. When this big conspiracy was taking place, this verse was spoken by Sukadeva Gosvami. He points out that a demon can lose everything because of his nefarious activities.

"O son of Prtha, those who are not deluded, the great souls, are under the protection of the divine nature. They are fully engaged in devotional service because they know Me as the Supreme Personality of Godhead, original and inexhaustible."
