We must see broader and humanistic perspective. Anything made others to do will boomerangs. If one believes that one religion elevates him spiritaully let him practice it. At the same time one should not critice or do damage to other practices. One should reach god through ones own practices. These practices can not be practiced by all. Please read An Autobiography of a Yogi:Paramahansa Yogananda, Aurobindo, Ramakrishna Paramahansa and Vivekananda. They preached spirituality to the west and made several of them their desiples.They have never forced any body to their life. They practiced and shown what is good to the humanity.
Unfortunately the religious politics in India spoiling the whole fabric of spirituality.
As long as Christianity and Islam treats Hinduism as caste system ridden and demonly, they may be treading on foolishness.
There are scores of christians and muslims folowing Yoga and Hindu system of Vastu. What it denotes. Then Why loathe Hinduism.
Why most of the women belonging to christainity and Islam practicing hindu practices of dress and way of life.
Please walk free of religion and try to see what is good in other religions.
