My beloved gurudev Srila Prabhupada, he would say that real spirituality is not about being a Hindu or a Muslim or a Christian or a Jew or a Buddhist or a Jain or a Sikh or a Zoroastrian or anything else. It's about cleansing our heart, it's about awakening the dormant love of God that is within us and being instruments of that compassion in our life in whatever we may do.
