Kali-yuga’s Degradation, the Advent of Kalki, and the Reset of the Yuga Cycle
त्रिंशद्विंशतिवर्षाणि परमायु: कलौ नृणाम् ॥ ११ ॥
triṁśad viṁśati varṣāṇi paramāyuḥ kalau nṛṇām
La durée maximale de la vie des êtres humains dans le Kali-yuga sera de cinquante ans.
This verse states that in Kali-yuga the maximum lifespan of humans is about fifty years (thirty plus twenty).
Śukadeva is listing the symptoms of Kali-yuga to help Parīkṣit understand the decline of human strength and virtue and the urgency of spiritual practice.
Remembering life’s uncertainty and brevity encourages sincere bhakti—using one’s time for hearing, chanting, and living dharmically rather than postponing spiritual life.
