Toh 477The Tantra of the Secret Ornament of the Moon

AN EXPOSITION OF THE TANTRA OF THE SECRET ORNAMENT OF THE MOON

Background

The Candraguhyatilakatantra (Tantra of the Secret Ornament of the Moon) is a tantric scripture belonging to the Vajrayāna tradition and recorded in the Kangyur—the collection of Buddhist scriptures translated into Tibetan from original Sanskrit sources. This tantra occupies the position Toh 477, demonstrating its importance within the system of the Tantra section’s most refined practices.

In the Vajrayāna tantric tradition, tantras are not general teachings but profound practical instructions intended for practitioners who have received empowerment from a qualified master (guru). The title “Secret Ornament of the Moon” symbolizes this Dharma method’s subtle and esoteric character—the moon (candra) in Tantra commonly represents mind (citta), the cool light of wisdom, and the purity of the mind’s essential nature.

Main Content

This tantra focuses on practices connected with the subtle-energy system (subtle body), particularly the application of dual wisdom to refine the energy points and energies (nāḍī and prāṇa). Here, the “ornament” (tilaka) is not merely a decorative mark on the forehead but refers to energy centers—convergence points of subtle vitality, commonly called cakras in the Indian tradition.

This Dharma method instructs practitioners in using deity yoga to transform the coarse mind into the light of wisdom. Through meditative practice (sādhana), practitioners employ internal visualization to activate the lunar points—subtle energy points associated with awakening.

The tantra teaches that the moon symbolizes the pure mind, which, when activated through correct practice, gives rise to invulnerable light—the light of emptiness and genuine wisdom. This is “secret” (guhya) because the practice is transmitted only within closed teachings, from master to disciple, and is not publicly disclosed, thereby preserving the integrity of the Dharma method.
