Kāla-vibhāga: The Divisions of Time from Atom to Brahmā, and the Lord Beyond Time
यामाश्चत्वारश्चत्वारो मर्त्यानामहनी उभे । पक्ष: पञ्चदशाहानि शुक्ल: कृष्णश्च मानद ॥ १० ॥
yāmāś catvāraś catvāro martyānām ahanī ubhe pakṣaḥ pañca-daśāhāni śuklaḥ kṛṣṇaś ca mānada
人の一日には昼に四つのプラハラ(ヤーマ)、夜にも四つのプラハラがあると数えられる。同様に十五日夜で一パクシャ(半月)となり、月には白分(シュクラ)と黒分(クリシュナ)の二パクシャがある。
This verse states that for humans, both day and night are each divided into four yāmas (time-watches).
In Canto 3, Chapter 11, Śukadeva is describing the Bhagavatam’s system of time measurement—from smaller units up to calendrical divisions—so Parīkṣit can understand cosmic time and its spiritual implications.
It encourages mindful living with sacred time-cycles—using waxing and waning lunar phases to structure sādhana, observances, and reflection on the passing nature of material time.
