In this fast moving world that bombards us daily with more information than we can handle, it is useful to take a break, so meditation and similar techniques are well worth practicing, but if anyone thinks they will lead to a spiritual experience, they will forever be dissatisfied.
For it is this physical universe–this material world, that truly awes us. The awe we feel when standing in a forest or gazing at the stars on a clear night is evoked by stars that are material, forests that are material. Only the material can ignite this sense of wordless wonder that is too often described as spiritual. That this material universe is awesome and remains more than we can ever fully comprehend does not imply that the incomprehensible must be some form of spiritualism.
Evolution programmed us to survive at any cost, not to know per se, but a look at our fangs and claws show how poorly we would fare if we had to depend on them for survival. Knowledge, ergo, a product of conscious thinking, just happens to be our weapon of choice.
