This volume is a continuation of the first, and so builds and expands upon the groundwork introduced there without backtracking, re-framing, or repetition.
Initially I thought the first volume would be more than enough for a beginner to work through before taking up any more. That was proven wrong as soon as reading the first few lessons here. They contain numerous practices and enhancements, many of which can be taken up very soon (ex. cosmic samyama, solar centering, spinal breathing enhancements, relational self-inquiry, etc.) if not immediately after starting out, without necessarily lengthening the time commitment overall.
The principle that is also elegantly illustrated with this latest edition is that the basic tools provided to the practitioner can, over time and with experience, uncover inner resources that help guide even the practice itself to deeper levels of refinement, and not just progress on the path. The author in effect shows here how this is done, by adding to the existing volume 1 baseline from his own vast experience and through the accumulating experiences of long-time practitioners of AYP.
These are some of the insights that can be expected, and that do become more evident, from AYP Volume 2, coming from such an organic, collaborative system, that on the one hand "stands on the shoulder of giants" of yoga, tantra, and nonduality, and on the other strives forward for the benefit of all.
