Questions pertaining to Kavana / Concentration which is most often an issue in prayer. There is another form of kavana which relates to intention which needs its own definition.

In both Jewish prayer and mitzvah observance there is an emphasis on refining the action by performing them with kavana, namely the act of concentrating wilfully on what is being done.

Take for example the Shemona Esrei prayer (see here):

Davening with kavana means that one should concentrate on the meaning of the words. One should not think of other matters while he recites the brachos of Shmoneh Esrei. When saying the bracha of Avos one should not think of other matters even between saying the words (Beiur Halacha OC 101 s.v. Hamispalel in the name of the Rashba).
