the little I know:
Kavanah is never measured in decibel level. One may not daven loudly in a manner that is disturbing to others. It is commonplace in many shuls that there are individuals who are so enamored with their own voice that they continually make themselves heard at the expense of others. Likewise, there is often a “rebbe” who puts on a display of answering ??? or ??? ???? ??? in a way which “appears” to be righteous but is really old fashioned ????. We must be constantly aware that true kavanah is completely ????? ????.
It is a great idea to do something in each and every tefila that is totally personal. One magid shiur would suggest to his talmidim that each bochur say something personal in every ???? ???? that was recited silently and his own language. Someone else suggested that everyone choose any part of davening, a bracha, a posuk, etc., study it, and make it their own. That would be always the place during which that individual would establish a connection to ???”?. hopefully, that would expand, but there is at least some place during tefila where the connection to ???”? occurs.
An excellent post that is worth repeating.
