Hindus .......more gods you believe in, the more successful you are in life"
This assertion is completely false. Hindus believe there is One God with many Names.
Is it really that hard to understand that each human mind can have it's own conception of what we call a $DIETY or $GOD. The oldest Hindu scripture and the foundation of this religion/philosophy (and later, it's offshoot Buddhism (Buddha was born a Hindu but then decided to start a fresh Philosophy, without some of the superstitious aspects that had crept into Indian society by then), the RigVeda (indeed the oldest extant texts in any Indo-European language) starts of saying essentially that there is One God, which People call by Many Names.
They call him Indra, Mitra, Varuna, Agni, and he is heavenly nobly-winged Garutman.
To what is One, sages give many a title they call it Agni, Yama, Matarisvan.
—Rigveda 1.164.46, Translated by Ralph Griffith
This makes this philosophy (that existed incidentally before any of the religions, even Hinduism as it was named later by the Britishers and other colonizers) intrinsically and naturally pluralistic (Pluralism, open minded and tolerant.
pluralism definition. A conviction that various religious, ethnic, racial, and political groups should be allowed to thrive in a single society. In metaphysics, pluralism can also mean an alternative to dualism and monism.
Indeed, not just tolerant, but accepting of other faiths, since it believes (not just believes, but practically tells the practitioner to experience the truth for him/herself by Direct experience/intuition through Yoga/meditation and other techniques and find out for oneself with the help of a spiritual Teacher) that practically each thinking mind can have it's own name, form and concept of the Truth (as they preferred to call it (that which is not False)), but the Absolute Truth (call it the Divine Mother (Hindus also worship the Divine in its Feminine form - Shakti or simply Divine Power lies beyond the conception of the normal planes of consciousness (those who have reached it describe it as Sat-Chid-Ananda, (translated it simply means the direct experience of that which is Existence-Knowedge-Bliss - Pure Consciousness, once again call it God, Shiva, Jesus, or by any other name, just don't kill each other over $IT) and can be experienced in higher planes of expanded consciousness.
This experience is pretty much each street level druggie is unconsciously craving and trying to kill/OD him/herself over instead of reaching it through safer, tried and tested means like (e.g. Yoga, because they take more persistence and effort. Also, Yoga is just a Path, as there are others, as Buddhism, Christianity, and other $RELIGIONS and what not theoretically, each person as on his own Spiritual Journey over lifetimes of Incarnations) that have helped millions of others reach it safely and surely in this very lifetime, if not the next, and the next, and the next, .... ad infinitum.
