“Devours all living beings” means “destroys all living beings.”

GLOSS. Other wives of the king stated that King Daśaratha was evil by speaking this verse and that he followed the conduct of the fools.

NOTE. Rejecting the association of the Supreme Personality of Godhead is certainly foolish as pointed out by Prabhupāda thus:

The fact is that every individual living entity is eternally part and parcel of the Supreme Lord, and both of them are very intimately related as friends. But the living entity has the tendency to reject the sanction of the Supreme Lord and act independently in an attempt to dominate nature, and because he has this tendency he is called the marginal energy of the Supreme Lord. The living entity can be situated either in the material energy or in the spiritual energy. As long as he is conditioned by the material energy, the Supreme Lord, as his friend, the Supersoul, stays with him just to get him to return to the spiritual energy. The Lord is always eager to take him back to the spiritual energy, but due to his minute independence the individual entity is continually rejecting the association of spiritual light. This misuse of independence is the cause of his material strife in the conditioned nature. The Lord, therefore, is always giving instruction from within and from without. From without He gives instructions as stated in Bhagavad-gītā, and from within He tries to convince the living entity that his activities in the material field are not conducive to real happiness. “Just give it up and turn your faith toward Me. Then you will be happy,” He says. Thus the intelligent person who places his faith in the Paramātmā or the Supreme Personality of  Godhead begins to advance toward a blissful eternal life of knowledge. (Bhagavad-gītā 13.23 purport)
