Do mantra in the physical aspects, the bodily struggles, the need for a stable core! Involve them in your naturally paced mental reminders that guide your body steadily and organicaly.
It is very easy to drift into the realm of logic trees, discovery and wonders, of personae and stories.
It is just as easy to think of a mantra, and switch from sweet daydream into empowering focus. Allow a focus on what already is: your skin, your bones, your muscles, the air traveling through your arteries and nourishing the multitude of inner organs that compose your body and make it a harmonious being.
Special note to self: “Do mantra in that rock solid, stable core you think of as impossible to ever achieve. As for every impossible piece, there is a piece of luck and magic.”
