Kriyā Yoga puts you into direct engagement with your subtle body’s channels, cakras, bindus, winds, elements, etc.
Kriyā Yoga is practiced as a stand-alone spiritual technology of liberation. In this mode, the Rudrānanda Kriya Yoga System is an excellent core practice of inner alchemy able to transform all limiting karmas when combined with Pure Motive and the Heart of Devotion to Path and Teacher.
The kriyā yoga component is like the engine that drives the empowerment of the visualizations and mantras of deities and manifests their experience in your time/space continuum. Deity Yoga practiced without the Kriyā Yoga component relies on sheer willpower and devotion to obtain the desired result. This can be an overly strenuous approach that dampens your enthusiasm, joy and pleasure found in the practice of deity yoga, thus resulting in little or no attainment.
