It is very important to generate a good attitude, a good heart, as much as possible. From this, happiness in both the short term and the long term for both yourself and others will come.
There is no need for temples, no need for complicated philosophies. My brain and my heart are my temples; my philosophy is kindness.
Whether one believes in a religion or not, and whether one believes in rebirth or not, there isn't anyone who doesn't appreciate kindness and compassion.
World belongs to humanity, not this leader, that leader or that king or prince or religious leader. World belongs to humanity.
-By Dalai Lama
