What are the forms or methods of achieving internal silence?
From my observation of people around and direct experience, there are actually many ways of achieving silence for the self. Here are the five categories and examples for each that I have come across. There are possibly more ways as well as categories.
1. Through the breath
2. Through touch
3. Through sound
4. Through visualisation
5. Through kinesthetic movement
6. Possibly through smell and taste (not observed or explored this enough to be sure)
