Sri Prapancasara Tantram - (Volume 2) - Sanskrit | Ram Chandra Puri/ Hindu Spiritual Book
• One well-known Tantrik text that is commonly credited to Shri Shankaracharya is the Prapanchasara Tantra.
• The five fundamental components of our universe—ether, air, fire, water, and earth—are referred to as prapanacha. Thus, the Science of the Essence of the Five Basic Elemental Principles is what the Prapanchasara Tantra represents.
• An authoritative Tantra text is Prapanchasara. Raghava Bhatta, the author of the renowned commentary (Bhashya) on Lakshmanacharya's Sharadatilaka Tantra, cites it as such.
• Kalicharana makes reference to it in his comments on the Shatchakara-nirupana.
