The book HaYom Yom, from Day to Day, daily is a source of deep insights that I find very profound...11 Adar I, 5765 - February 20...

The following is well-known and is a tradition, regarding the Kavanot
(mystical "intentions") in Davening [prayer]:

For those intellectually incapable of meditating on those Kavanot
(either because they lack knowledge, or because they cannot
remember the specific Kavanot during prayer) it is sufficient
that they keep one general Kavana in mind:

That his prayer be heard by G-d, with all the Kavanot described in the
Kabala literature.

For more on Kavanot, see here (Medatative) and see this post about Rav Kaduri.
