Swami Sivananda said that he served all religions, cults, faiths and creeds - and directed other Yogis to do the same. "The world is wicked, not for want of truth, nor on account of religions; but, alas, it is wicked for the lack of true followers of these ideals and religions. Place the practical tenets of their own religion before the followers of that religion, and devise ways and means of enabling them to express these tenets in their daily life. Without practice, idealism creates fatalism in man. Unless knowledge alters one's life, it is useless. Selflessness and love are not creeds to be taught, but ideals to be exemplified, demonstrated and radiated. Therefore, let everyone practice his own religion and strive to attain the goal. Let religion create saints and Yogins, rather than Mandirs (Hindu temple), Masjids (Mosque) and Churches."
This act of Bhakti Yoga is increasingly necessary. "At the present moment all religions contain a mixture of truth, which is divine, and error which is human. The fundamentals or essentials of all religions are the same. There is difference only in the non-essentials. The apparent differences in religions are due to a misconception or misconstruction of the long-forgotten truth of the Vedas on which they are ultimately founded. All systems of religion are equally divine and true. The conflicting points are all due to misconception and misconstruction of truths on account of prejudice, bigotry, lack of purity of heart and subtlety and purity of intellect, and perverted condition of the intellect of people."
Do you have the strength of heart to serve your neighbors and help them achieve the purpose of their religious practices? Can you place your own beliefs, values and gods upon the altar of a foreign god for the betterment of your fellow beings? Can you feel equally comfortable in a Church, a Mosque, or Temple? Equally comfortable among strangers, your neighbors, your friends and family? If your weak heart would favor one over the other, urge yourself toward better practice. None, but Nobody, should lack your Sraddha.
