Adhyaya 23: श्वेत-लोहित-पीत-कृष्ण-विश्व-कल्पेषु रुद्रस्वरूप-गायत्री-तत्त्ववर्णनम्
मत्कृतेन च वर्णेन कल्पो वै लोहितः स्मृतः तदा लोहितमांसास्थिलोहितक्षीरसंभवा
matkṛtena ca varṇena kalpo vai lohitaḥ smṛtaḥ tadā lohitamāṃsāsthilohitakṣīrasaṃbhavā
By the hue brought forth through Me, that aeon is remembered as the “Lohita Kalpa,” the Red Kalpa. In that time, beings arose in forms connected with red blood, flesh, bone, and ruddy milk—coming forth according to that coloration.
Suta Goswami (narrating the Purana; internal teaching attributed to the cosmic Lord’s agency)
It frames creation as arising from the Lord’s own power (Pati), supporting Linga worship as devotion to the transcendent source from whom all embodied forms (pashu) emerge.
Shiva is implied as the causal ground whose śakti determines the “color” (quality) of a kalpa—showing Him as Pati, the sovereign cause governing manifestation and embodiment.
No specific puja-vidhi is stated; the takeaway is contemplative Pashupata orientation—meditating on Shiva as the origin of the tattvas and bodily constituents, loosening pasha (bondage) through right knowledge.
