Physical Benefits : It is easy to imagine that moisture retention and general circulation would be enhanced creating lustrous skin, but this practice actually accomplishes much more. The combined knowledge of Western and Eastern sensibilities professes that energy blockages are the foundations of all disease, because they produce the ill formed cells commonly called free radicals. Specifically within the ayurvedic sensibility, we all have seven dhatus or levels of bodily tissue that are responsible for the entire structure of the body, and its organs and systems. Regular practice oof abhyanga energetically penetrates to progressively deeper dhatus, removing blockages of energy. So the prolonged practice of abhyanga effectively supports the body on this cellular level, too.

Psychological and Spiritual Benefits: What we more consciously experience when we do abhyanga regularly, simply a feeling of calm, well-being. Just like when one practices yoga, eats well, or prays, we are not conscious of some enormous effect. It is because of the nature of the mind-body-spirit relationship.
