Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
कनकाभे तथागारसंनिभे सुसिते ऽपि वा द्वादशादित्यसंकाशे चन्द्रबिम्बसमे ऽपि वा
kanakābhe tathāgārasaṃnibhe susite 'pi vā dvādaśādityasaṃkāśe candrabimbasame 'pi vā
Puede ser de tono dorado, o semejante a una mansión de cristal resplandeciente; puede ser de blancura perfecta; puede arder como el fulgor de doce soles; o ser sereno y fresco como el disco de la luna.
Suta Goswami (narrating to the sages of Naimisharanya; describing accepted Linga forms/appearances)
It legitimizes multiple auspicious visual forms of the Linga—golden, crystal-like, white, solar-brilliant, or moon-calm—showing that Linga-puja is not restricted to a single material or appearance, but to devotion toward Pati (Shiva).
Shiva-tattva is indicated as both tejas (solar brilliance) and saumya (lunar serenity): the Linga can appear as intense light or tranquil purity, pointing to the Lord who transcends and yet pervades all qualities while liberating the pashu from pasha.
It supports dhyāna in Linga-puja: the practitioner may visualize the Linga as blazing like many suns or calm like the moon, using that chosen form as an aid for one-pointed Pashupata-style contemplation of Shiva as Pati.
