Hello Katrin and Alessia,
Sharawa’s instruction is really applicable to this situation. Letting them come and go really helps us to cultivate stability in meditation. The ability to be with thoughts and emotions in a gentle way can be hard especially when many myriad emotions and thoughts come and go.
Thich Nhat Hanh uses the word “stopping” as the operative quality of what can be called shamatha or calm-abiding. So what are we “stopping?” We try to stop our long-held habit of being carried away by our thoughts and physical and mental sensations. We do this in a gentle way again and again. We often have strong habits to jump on thoughts, to analyze and adjudicate our thoughts and subsequent reactions to those them.
This really helps me!
