Vashi Yoga -Awaken the Inner Current of Longevity.
Discover the living tradition of Vashi Yoga - the Siddha science of prāṇa, Tantra, and inner alchemy- reimagined for the modern seeker through the Siddha Longevity Institute.
What is Vashi Yoga?
Vashi Yoga is the ancient Tamil–Shaiva science of self-governance through breath and awareness.
“Vashi” means to command, to harmonize, to master.
It is the yoga of sovereignty — where consciousness governs energy, and energy shapes destiny.
Our mission is to revive the Siddha technologies of longevity, consciousness, and self-healing through structured learning, live guidance, and measurable transformation.
