In Canto 3, Chapter 11, this verse explains that the interval between sandhyā and its fractional portion (sandhyā-aṁśa) is counted in hundreds of units, and learned authorities designate such measured spans as part of yuga-based time reckoning.
The verse defines yuga not only as a time-measure but as an age in which dharma is arranged and manifested in a particular way—implying that moral and spiritual order is understood in relation to cosmic time cycles.
It encourages aligning one’s daily discipline (dharma) with regular “junctions” and rhythms—using transitions (like dawn/dusk) for prayer, reflection, and recommitment to spiritual practice.
