It frames Ketu as a cosmic force of cessation—reminding the seeker that all embodied conditions end, thereby turning the mind toward vairāgya (dispassion) and mokṣa-oriented living.
By emphasizing the inevitability of endings, the verse indirectly urges reliance on the deathless refuge—Bhagavān—so devotion becomes the stable anchor amid change and dissolution.
Jyotiṣa (Vedic astrology): it identifies Ketu/Dhūmaketu with specific attributes and a feared ‘ending-making’ influence, a basis for interpreting graha effects and considering śānti or devotional remedies in practice.
