Sit in meditation ! But do not think ! Look only at your mind ! You will see thoughts coming into it ! Before they can enter, throw these away from your mind till your mind is capable of entire silence.
When you inquire 'Who am I?' if you are honest, you'll notice that it takes you right back to silence instantly. The brain doesn't have an answer, so all of a sudden there is silence.
Mental happiness is more important than physical comfort. Physical comfort comes from the material. But material facilities cannot provide you with peace of mind.
To be silent is not to lose your tongue. On the contrary, it is only through silence that one can discover something new to talk about. One who talked incessantly, without stopping to look and listen, would repeat himself ad nauseam.
