Thoughts as Focal Support
As for the way of doing it in the mahāmudrā, one takes any thought that occurs-whether it be a general thought, thinking associated with unpleasant states, a thought taking the form of labeling, or thinking associated with habitual patterns-and looks nakedly into its essence and rests perfectly at ease within that.
When dealt with in this way, the thoughts themselves become the focal support for the shamatha. So that's how to work with this.
