As Madhu Bazaz Wangu pointed out, Buddhism is the way to spiritual discovery (8). Buddhism, as a non-theoretical religion, their disciples follow the principle of monotheism and prove that they only believe in one god. Siddhartha Gautama, mostly known as Buddha - opened the enlightenment - the god Buddhist believes. As Ivan wrote, Siddhartha practiced strict self denial and meditation before he reached Nieana (idea of ending a painful path) (8). Siddhartha concluded that in order to reach Nieana, people should be able to eliminate desire by making correct and correct thinking.
But what kind of way should you follow? We have a lot. There are traditional general roads such as Judaism, Christianity, Muslim, Buddhism. There are modern spiritual movements like Scientology and Wicca. But all these roads have something in common. The source file - the Bible itself - tells us what to believe, how to practice it, and how to approach daily life. The public can easily get an open pass and is usually well understood. People choose the open information they need at that time
Tantra provides a way of true liberation and awakens our reality. But even in history, not everyone chooses to choose the road. Indeed, like most spiritual examples in human history, a more general approach is to understand ways to yield to spiritual needs. Tantra supports this method very clearly. Unlike the religious tradition of the time (Buddhism, Jainism, and various Vedas' religions), Tantra opened its teachings, wisdom and practice to all: all gender (women are particularly respected in Tantra ), All language groups, all religions (Tandara) are regarded as spiritual practice styles, not individual religions), all races, all castes. Furthermore, it is clear that not everyone is on the way of advanced mental awakening. In classical form, Tantra is science, and like science, it creates a "technology" of practical release.
Mentally "waking" people see the world's major religions as different paths of the same mountain. I believe that purely scientific worldview combined with mental exploration and practice is another way of the mountain. This is hard to see. Scientific spirituality reduces the narrator of the story and the time to spread its cosmology is much less. So far, Carl Sagan is probably the best attempt. Supernatural tendencies often see a purely scientific world, a world without a supernatural world, a world without magic, wonders, flickering, and mysterious colors. I think that the view of things is limited. In contrast to the supernatural world of Hinduism, Buddhism and Christianity, the natural world is its own journey.
