You can develop the right attitude toward others if you have kindness, love and respect for them, and a clear realization of the oneness of all human beings.
Once we have a firm practice of compassion our state of mind becomes stronger which leads to inner peace, giving rise to self-confidence, which reduces fear. This makes for constructive members of the community. Self-centredness on the other hand leads to distance, suspicion, mistrust and loneliness, with unhappiness as the result.
Those who like myself, consider themselves to be followers of Buddha, should practice as much as we can. To followers of other religious traditions, I would like to say, 'Please practice your own religion seriously and sincerely.' And to non-believers, I request you to try to be warm-hearted. I ask this of you because these mental attitudes actually bring us happiness.
