Tenzin Gyatso, 14th Dalai Lama Quote

The most important thing is practice in daily life; then you can
know gradually the true value of religion. Doctrine is not meant for
mere knowledge, but for the improvement of our minds. In order to do
that, it must be part of our life. If you put religious doctrine in
a building and when you leave the building depart from the practices,
you cannot gain its value.
