Transmission Meditation is a simple group meditation that provides both a dynamic service to world and powerful personal spiritual development. It is a combination of two yogas: Karma yoga (the yoga of service) and Laya yoga (the yoga of the energies of the chakras - Laya yoga is a specialised form of Kriya yoga).
There is a global network of Transmission Meditation groups. The Edinburgh group meets three times a week, on Sundays & Mondays and Wednesdays. It is a non-denominational activity, is free to do and newcomers are especially welcome :)
