Due to the recent (last 100 years, perhaps) backlash against religion in general, a lot of interesting philosophical ideas get ignored or rejected just because they are explained in terms of religious beliefs. In my mind a religion is a set of beliefs concerning the cause, nature, and purpose of your existence that helps you define your way of life. We all have our beliefs and we make that a part of the life we lead. As the beliefs get shared and adopted by more and more people, then that religion starts becoming popular and slowly gets formalized into rituals and commandments. However, unless it appeals to your rational intellect in some way or form (faith / fear / logical reasoning / scientific reasoning, etc.), you will struggle to make it a part of your life.
A very simple way to look at some of the philosophies... Dvaita I am the wave, you are the ocean. The body, mind and intellect is separate from the objects it perceives. This separation of the perceived from the perceiver is Dvaita. Vishishtadvaita I, the wave, am but a part of you the ocean. The body, mind and intellect are actually a part of the object it perceives. The Brahman encompasses the perceiver in the body, mind and intellect. Advaita You, the ocean and I, the wave are nothing but water, perceived. The body, mind and intellect and the objects it perceives are in fact all the same and unreal and a result of the projection of the one reality of Brahman, a projection caused due to the perception itself.
