When it is desired to promote the prosperity of the nation, every one of you must gather into yourself all the spiritual resources that you can. This implies that all the spiritual inclinations, beliefs and urges which are now feeble and dissipated must be united and reinforced. As part of religions, many creeds and cults may exist just as many branches are present in a tree. You should not condemn them as wrong and no branch should fight against another or compete with another.
Realize the truth in the maxim, “Ekam Sath; Vipraah Bahudhaa Vadanthi” (Only One exists; the wise describe it in many ways). ( from Bhagvad Gita)
