Adhyaya 40: Kali-yuga Lakshana, Yuga-sandhyamsha, and the Re-emergence of Dharma
तस्मादायुर्बलं रूपं कलिं प्राप्य प्रहीयते तदा त्वल्पेन कालेन सिद्धिं गच्छन्ति मानवाः
tasmādāyurbalaṃ rūpaṃ kaliṃ prāpya prahīyate tadā tvalpena kālena siddhiṃ gacchanti mānavāḥ
Therefore, with the coming of the Kali-yuga, lifespan, strength, and bodily beauty decline. Yet in that very age, human beings can attain siddhi—spiritual accomplishment—within a short time, through concentrated devotion to Pati (Lord Śiva) and the disciplines that cut the pāśa binding the paśu (the individual soul).
Suta Goswami (narrating to the sages of Naimisharanya)
It frames Kali-yuga as materially degenerative yet spiritually efficient: sincere Linga-centered devotion and Shaiva sadhana can yield rapid siddhi even when human vitality declines.
By implication, Shiva as Pati remains unchanged across yugas and is accessible even in Kali; the soul (pashu) can quickly move toward perfection by turning to Him and loosening bondage (pasha).
A general emphasis on time-efficient Kali-yuga sadhana—devotion (bhakti) and disciplined Shaiva practice aligned with Pashupata-style inner purification—rather than a specific single rite.
