“The real religion of humankind can be said to be spirituality itself, because mystical spirituality is the origin of all the world religions. If this is so, and I believe it is, we might also say that interspirituality – the sharing of ultimate experiences across traditions – is the religion of the third millennium. Interspirituality is the foundation that can prepare the way for a planet-wide enlightened culture, and a continuing community among the religions that is substantial, vital and creative. Interspirituality is not about eliminating the world’s rich diversity of religious expression. It is not about rejecting these traditions’ individuality for a homogeneous super-spirituality. It is not an attempt to create a new form of spiritual culture. Rather, it is an attempt to make available to everyone all the forms the spiritual journey assumes.”
