Under the bright sun, many of us are gathered together with different languages, different styles of dress, even different faiths. However, all of us are the same in being humans, and we all uniquely have the thought of 'I' and we're all the same in wanting happiness and in wanting to avoid suffering.
I always emphasize that it is much safer and better to keep one's own religious faith. The other major religions are thousands of years old and have long traditions.
Since we desire the true happiness that is brought about by a calm mind, and such peace of mind arises only from having a compassionate attitude, we need to make a concerted effort to develop compassion.
