"The nihilist point of view is one of the biggest problems for all beings. Since the nihilist point of view distorts perception through its singular focus on substance, intangible spiritual phenomena cannot be seen clearly and intangible continuous mind cannot be recognized.
We may say we can only believe in what can be experienced or proven, but actually we believe selectively in what we have not experienced or proven as long as it is compatible with our other conceptions. We accept and use intangible abstractions of intangible times, places, and circumstances to support what we think is tangibly true, turning the intangible to the tangible through our conception. Because we are only interested in our own version of reality, we miss the potential opportunity to connect tangible qualities to intangible qualities through wisdom's influence."
