Matsya Purana — Manvantaras
परमायुः शतं त्वेतन् मानुषाणां कलौ स्मृतम् देवासुरमनुष्याश्च यक्षगन्धर्वराक्षसाः //
paramāyuḥ śataṃ tvetan mānuṣāṇāṃ kalau smṛtam devāsuramanuṣyāśca yakṣagandharvarākṣasāḥ //
In Kali Yuga, the maximum lifespan of human beings is remembered to be one hundred years. Here are mentioned the gods, demons (asuras), humans, as well as the Yakṣas, Gandharvas, and Rākṣasas.
This verse does not describe Pralaya directly; it frames Kali Yuga conditions by stating the traditionally remembered human maximum lifespan (100 years) and listing classes of beings within the cosmic order.
By emphasizing the shortened, limited span of life in Kali Yuga, it supports the Purāṇic ethical urgency: kings and householders should prioritize dharma, disciplined conduct, and timely performance of duties rather than postponing righteous action.
No explicit Vāstu or temple-construction rule appears in this verse; its practical ritual takeaway is the Kali Yuga premise of limited lifespan, often used in Purāṇic contexts to encourage regular worship, charity, and prescribed rites without delay.
