There is a spiritual hunger in many people.
The problem is that religions are not spiritual.
Religions are about faith & dogma, not spiritual wisdom & spiritual enlightenment.
The religions of the world are all dying as the era of religion is giving way to an era of spirituality.
Scientific dogmatic materialism is itself a reaction, and mirror, of religious dogmatic anti-materialism.
Both are archaic world views that no longer have any real basis.
Spirituality though allows science and spirit to be reconciled - as an individual who experiences spiritual enlightenment is able to base their experiences on direct evidence - which allows science and spirituality to be linked.
The mental, physical, psychological, social effects of spiritual enlightenment in an individual prove its vailidity on a scientific basis predicated on measurable evidence - and hence transcends scientific materialist dogma that repudiates the divine and religious faith dogma that denies personal enlightenment for dogma and faith without personal experience.
