Matsya Purana — War of Devas and Asuras; Birth of Aurva Fire; Countering Tamasī Māyā through ...
एकस्त्वमनपत्यश्च गोत्रजो ऽन्यो न वर्तते कौमारं व्रतमास्थाय क्लेशमेवानुवर्तसे //
ekastvamanapatyaśca gotrajo 'nyo na vartate kaumāraṃ vratamāsthāya kleśamevānuvartase //
You are alone and without offspring; no other kinsman of your lineage remains. Yet, having undertaken the vow of lifelong celibacy, you are only pursuing hardship.
This verse is not about pralaya; it focuses on dharma in human life—lineage continuity and the appropriateness of vows like lifelong celibacy.
It stresses responsibility toward family and lineage: when one is the sole remaining member, refusing household life and progeny through an ill-timed celibacy vow is portrayed as self-imposed suffering and neglect of social duty.
No Vastu/temple-architecture rule is stated here; the ritual point is the ethical evaluation of a vrata (kaumāra-vrata) and whether it fits one’s life-situation.
