Hindu Tantra and kuṇḍalinī
Explanation
Hindu tantra is a broad philosophical and practical movement that emerged in India between the fifth and twelfth centuries approximately, parallel to the development of Buddhist tantra. Its distinctive feature: integrating the totality of human experience (body, energy, desire, emotion, senses) into the spiritual path, rather than renouncing it. The world is not illusion to be transcended (as in some readings of Vedanta); it is the manifestation of divinity (Shakti, the feminine creative energy), and can be a tool of realisation.
The central concept of tantra is the polarity Shiva-Shakti. Shiva is pure consciousness, motionless, empty. Shakti is dynamic, manifesting, creative energy. All reality is the dance between Shiva and Shakti. The human microcosm reflects the macrocosm: in the body, Shiva resides at the crown and Shakti (as kuṇḍalinī) sleeps coiled at the base of the spine. The tantric aim is to awaken kuṇḍalinī and have her ascend through the chakras until she unites with Shiva at the crown, which constitutes supreme realisation.
The system of chakras (energy centres) and nāḍīs (energy channels) is fundamental in tantra. The seven main chakras (mūlādhāra, svādhiṣṭhāna, maṇipūra, anāhata, viśuddha, ājñā, sahasrāra) are associated with psychological, emotional, energetic and spiritual functions. Energy flows through nāḍīs, the three principal ones being suṣumnā (central channel), iḍā and piṅgalā (lateral channels). Awakening kuṇḍalinī involves opening suṣumnā and progressively activating the chakras.
Tantric practices are varied and often secret, transmitted from master to disciple. They include mantras (sacred syllables), yantras (geometric meditative diagrams), mudrās (gestures), specific āsanas, prāṇāyāma (breath), complex visualisations, and in certain currents rituals with a consort (maithuna) or transgressive substances. The left-hand branch (vāmācāra) is the most transgressive, while the right-hand (dakṣiṇācāra) adapts the principles without the most controversial aspects.
For the theory of consciousness, tantra offers an energetic-bodily model very different from the Western cognitivist one. Consciousness is not only in the brain; it is distributed in a subtle body with its own architecture of centres and channels. Transformation of consciousness is achieved by working with this energetic architecture. These ideas have generated interest in integrative medicine, bioenergetics, and dialogues with neuroscience on the autonomic nervous system and breath, although the exact correspondence between classical anatomical chakras and biological structures continues to be debated.
The influence of tantra has been vast: it shaped much of medieval and contemporary Hinduism, generated hatha yoga as a physical branch, influenced Buddhist tantra (Tibetan vajrayana, Japanese shingon), and in the West has been adapted in diverse forms (from modern kundalini yoga to more or less serious interpretations in New Age spirituality). Contemporary masters such as Muktananda, Gopi Krishna or Swami Satyananda have given modern expression to these teachings, with contributions and also controversies.
