Silence and emptiness I never understood silence or emptiness in Buddhism and how is experiencing them beneficial?.Is it a way for experiencing the arising of experience ?
Silence in Buddhism refers to Citta Visuddhi. This means the purification of the mind, or quietening of the mind. It doesn't mean no sound. This is when the mind attains highly concentrated states called the Jhanas. When the mind is in these states, your defilements are silenced or subdued. This is a good base for the development of insight meditation.

'Emptiness' is a nature of all realities. It doesn't mean empty in the literal sense. It means being empty of a self or a soul or an entity. This is a truth one realizes with insight meditation. It is one of the Three characteristics of all condition phenomena. Realizing them lead to enlightenment.
