The Vajra or thunderbolt is the weapon of Lord Indra, the King of the Gods. In Sanskrit the term 'Vajra' relates to firm, determined & decisive Awareness. In yogic context, Vajra refers to Vajra Nadi (Energy Channel), which governs the uro-genital system and is responsible for sexual behaviour. The control of the Vajra Nadi sublimates sensual energy and channelise it towards activating higher brain centres. All Yogic practices are aimed towards this.
