संन्यासमण्डलविधिवर्णनम्
Sannyāsa Maṇḍala Vidhi—Procedure for the Renunciate Mandala
श्यामेन पीठं पीतेन श्रीकण्ठं च विचित्रयेत् । अमरेशं महाकालं रक्तं कृष्णं च तौ क्रमात्
śyāmena pīṭhaṃ pītena śrīkaṇṭhaṃ ca vicitrayet | amareśaṃ mahākālaṃ raktaṃ kṛṣṇaṃ ca tau kramāt
One should depict the pedestal (pīṭha) in dark blue, and paint Śrīkaṇṭha in yellow. Then, in due order, Amareśa is to be shown in red, and Mahākāla in black.

Tattva Level: pati
Shiva Form: Nīlakaṇṭha
Sthala Purana: The verse is primarily iconographic (varṇa-vidhi) for a yantra/maṇḍala; it does not narrate a jyotirliṅga origin, though Mahākāla coloration aligns naturally with Ujjain’s Mahākāla tradition.
Significance: Color-vidhi functions as upāsanā-aṅga: correct visualization is treated as aiding concentration (ekāgratā) and mantra-siddhi.
The verse gives dhyāna-oriented iconographic cues—color and form—so the devotee can steady the mind on Saguna Shiva; such focused contemplation supports purification (śuddhi) and opens the way to Shiva’s grace leading toward liberation.
It aligns with Saguna upāsanā: Shiva is approached through specific manifestations (Śrīkaṇṭha, Amareśa, Mahākāla) with prescribed colors, aiding visualization and ritual depiction alongside Linga worship as complementary modes of devotion.
A practical takeaway is dhyāna (visual meditation) and pratimā/yantra-style depiction: contemplate or paint the forms with the stated colors in sequence, supporting mantra-japa and pūjā with a stable inner image of Shiva.
