In the essence of Mahamudra course that I'm talking YMR explains the three levels of transformation, the view (cognitive), meditation (emotional), and application (habitual).
We first approach the idea of buddah nature with the intellect. Then through meditation we bring develop an emotional relationship with it, sometimes enjoying it, sometimes not. Finally, through application in life, to our problems, we have the kind of direct realization that is self-generating. We become one with Mahamudra.
That is transformation.
When eating, cleaning, living, sleeping become Mahamudra, that is retirement from Samsara.
