Each religion has helped mankind. Paganism increased in man the light of beauty, the largeness and height of his life, his aim at a many-sided perfection; Christianity gave him some vision of divine love and charity; Buddhism has shown him a noble way to be wiser, gentler, purer, Judaism and Islam how to be religiously faithful in action and zealously devoted to God; Hinduism has opened to him the largest and profoundest spiritual possibilities.

There is a true feminist movement in Buddhism that relates to the goddess Tārā. Following her cultivation of bodhicitta, the bodhisattva's motivation, she looked upon the situation of those striving towards full awakening and she felt that there were too few people who attained Buddhahood as women. So she vowed, 'I have developed bodhicitta as a woman. For all my lifetimes along the path I vow to be born as a woman, and in my final lifetime when I attain Buddhahood, then, too, I will be a woman.'
Americans are interested because they are open-minded. They have an education system that teaches them to find out for themselves why things are the way they are.
