Adhyaya 40: Kali-yuga Lakshana, Yuga-sandhyamsha, and the Re-emergence of Dharma
उत्सीदन्ति नराश्चैव क्षत्रियाश् च विशः क्रमात् शूद्राणां मन्त्रयोगेन संबन्धो ब्राह्मणैः सह
utsīdanti narāścaiva kṣatriyāś ca viśaḥ kramāt śūdrāṇāṃ mantrayogena saṃbandho brāhmaṇaiḥ saha
やがて人々は衰え、クシャトリヤもヴァイシャもまた段階的に没落する。さらにマントラの誤用によってシュードラがブラーフマナと結びつき、社会秩序の境界が乱れてゆく。
Suta Goswami (narrating the Purana to the sages at Naimisharanya; contextual description of decline in dharma)
It frames a Kali-yuga backdrop where dharma weakens and mantra-discipline becomes confused—implying that Linga-puja requires proper niyama (restraint), right transmission, and purity of practice to remain spiritually efficacious.
Indirectly: when social and ritual order collapses, refuge is sought in Pati (Shiva) as the stabilizing principle beyond decay; Shiva-tattva remains pure while pashus (souls) become further entangled through disorder and misapplied rites.
Mantra-yoga (mantra application/discipline) is highlighted—warning that mantra without proper adhikara (qualification), guidance, and observance can lead to dharmic confusion rather than liberation.
