Spirituality is not neccessarily exclusive: it can be and in its fullness must be all-inclusive. But still there is a great difference between the spirituality and the purely material and mental view of existence.
The spiritual view holds that the mind, life, body are man’s means and not his aims and even that they are not his last and highest means: it seems them as his outer instrumental self and not his whole being.
It sees the infinite behind all things finite and it adjudges the value of the finite by higher infinite values of which they are the imperfect translation and towards which. to a truer expression of them., they are always trying to arrive.
This alerts necessarily our whole normal view of things: even in preserving all the aims of human life, it will give them a different sense and direction.
