Brahmā’s Day, the Four Pralayas, and the Supreme Shelter Beyond Cause–Effect
चतुर्युगसहस्रं तु ब्रह्मणो दिनमुच्यते । स कल्पो यत्र मनवश्चतुर्दश विशाम्पते ॥ २ ॥
catur-yuga-sahasraṁ tu brahmaṇo dinam ucyate sa kalpo yatra manavaś caturdaśa viśām-pate
Ang isang libong siklo ng apat na yuga ang bumubuo sa isang araw ni Brahmā; ito ang tinatawag na kalpa. O Hari, sa panahong iyon ay may labing-apat na Manu na salit-salit na dumarating at lumilipas.
This verse states that one day of Brahmā equals one thousand cycles of the four yugas (caturyuga-sahasra), and that duration is called a kalpa.
In Canto 12, Śukadeva is describing cosmic time and dissolution (pralaya). Explaining the kalpa and the sequence of Manus helps Parīkṣit understand how creation is structured and how vast time is under divine governance.
Knowing the vast scale of cosmic time cultivates humility and detachment, encouraging one to prioritize bhakti and spiritual practice over temporary achievements.
