Night, the Moon, Mars, and Saturn are regarded as always harsh; some others too become harsh when their influence is disturbed. In the dark fortnight (kṛṣṇa-pakṣa) they are considered severe, while in the bright fortnight (śukla-pakṣa) they are considered gentle—this is the view of the wise regarding the strength of Time (kāla-bala).

FAQs
It teaches that spiritual and ritual actions should respect kāla (time) and its strength, since timing—especially lunar fortnight dynamics—affects the ease or intensity (saumya/krūra) of outcomes.
