Vajrayana
Definition
Vajrayana — the "Diamond Vehicle" or "Thunderbolt Vehicle" — is the tantric form of Mahayana Buddhism preserved most fully in Tibetan, Mongolian, Bhutanese, and related traditions. It arose in India around the 7th–8th centuries CE and was transmitted to Tibet through a succession of Indian masters (Padmasambhava, Naropa, Tilopa, and others). It represents one of the most sophisticated and extensively documented tantric systems in the world.
Vajrayana employs a distinctive methodology: visualisation of deities, mantra recitation, mudra, ritual, and in its advanced stages, specific breath and energy practices (such as the Six Yogas of Naropa, which include tummo inner-heat practice). The foundational premise is that the energy of all experiences — including difficult emotions, physical sensation, and even death — can be used as a path rather than suppressed or escaped.
Where the word comes from
From Sanskrit vajra (वज्र — diamond or thunderbolt, the indestructible weapon of the deity Indra; also a symbol of the nature of reality: clear, sharp, indestructible) + yāna (यान — vehicle or path). The compound thus means the indestructible or diamond vehicle. Vajra in Tibetan is dorje (rdo rje), and the tradition is also called Tantrayana or Mantrayana in different contexts.
In Tantra Clinic practice
Tantra Clinic draws selectively from Vajrayana — specifically from the breath and inner-heat practices that have been extracted from their ritual context and taught in secular or semi-secular form by teachers such as Wim Hof (tummo) and others. We are transparent about the source and clear about what we are and are not transmitting. We teach the breath mechanics and the somatic effects; we do not claim to transmit Vajrayana lineage, which requires initiation, a qualified teacher, and a structured preparatory curriculum.
