Only in the Roman Empire and in Spain under Arab domination has culture been a potent factor. Under the Arab, the standard attained was wholly admirable; to Spain flocked the greatest scientists, thinkers, astronomers, and mathematicians of the world, and side by side there flourished a spirit of sweet human tolerance and a sense of purist chivalry. Then with the advent of Christianity, came the barbarians.
Let us have love and more love; a love that melts all opposition, a love that conquers all foes, a love that sweeps away all barriers, a love that aboundeth in charity, a large-heartedness, tolerance, forgiveness and noble striving, a love that triumphs over all obstacles.
The only possible basis for a sound morality is mutual tolerance and respect: tolerance of one another’s customs and opinions; respect for one another’s rights and feelings; awareness of one another’s needs.
We cannot learn real patience and tolerance from a guru or a friend. They can be practiced only when we come in contact with someone who creates unpleasant experiences. According to Shantideva, enemies are really good for us as we can learn a lot from them and build our inner strength.
