The conventional materialist mode has very serious consequences in terms of how we live our lives, and how we treat other species and the natural world. It leads to a devaluation of life—of our own lives, of other species' and the Earth itself..a spiritual worldview can change our relationship to the world. It can engender a reverential attitude to nature, and to life itself. It can heal us, just as it can heal the whole world.
Where there is spirituality there is freedom, but religion is rigid. To be spiritual you have to step aside from the belief and go more into knowing, which gives you a greater freedom, including the freedom to question. Unless you question you're not going to get past the beliefs.
