Any thought, prayer, or feeling, when repeated often enough—and with deep feeling—can ultimately be felt going on and on, by themselves through the momentum created by rhythm and repetition. In the mindful experience of prayers and subtle sensations going automatically, in the background of the mind, an opening to finer and deeper realms of subtlety is created.
There is then a sense of touching into, tuning into a deep underground resonance that has the ongoing prayer and feeling embedded into it. Understand what is being offered here: a way for prayers and corresponding feelings/sensations to expand deep into the bedrock Hum of Creation!
In the beginning this need only be an initial recognition of how the inner resonance (felt as the overall sensation of the body) naturally draws the mind’s focus within…providing an easy entryway to finer and finer realms of subtlety.
