Vintner and others,
I am also very interested in learning Sw. Rama's description of Laya Yoga. that he outlines as a kind of Nada Anusadhana more akin to Shabda procedures with their Anahata sounds than to Laya Yoga in either its vaidika or tantrika form, which both require vivid visualization and highly developed mastery of pranayama. And also vaidika and tantrika forms of laya yoga, where might I learn these?
