Kālacakratantra

A Buddhist Tantra text contains five paṭalas (chapters) that deal with Buddhist cosmology, the Kālacakra calendar, the birth and death of universes, the birth of humans, the human body and its functions, the indriyas, the six energy centers (chakras) in the body, ten vital energies, energy channels, abhiṣeka of Kālacakra, yoga, meditation on the maṇḍala, and many other topics. It is said that the Kālacakra teaching was taught by Śākyamuni Buddha and was known as the Root Kālacakra Tantra, or Paramādibuddhatantra. Later, the Śambhala King Suchandra wrote a commentary on it; unfortunately, neither of these texts has survived. According to tradition, the Śambhala King Mañjuśrī-Yaśas composed the Laghukālacakratantra based on the preserved parts of the earlier work. This text is important for Tantric Buddhism, especially for followers of the Kālacakrayāna. The five chapters are: Lokadhātupaṭala (folio 22a), Adhyātmapaṭala (folio 45a), Abhiṣekapaṭala (folio 72a), Sādhnapaṭala (folio 101b), and Jñānapaṭala (folio 132a).
