There is no such thing as a non-spiritual experience. What is it that would have such an experience? We like to divide and categorize our lives. This habit makes us imagine that sometimes we have regular experiences and other times we have spiritual experiences. Spiritual experiences tend to feel really good. If we eat delicious food, we say it tastes like heaven. When we are so filled with joy that we can barely contain ourselves, we think that we are having a particularly spiritual experience.
In Zen and various other religions and philosophies there is a great deal of emphasis placed on the awakening experience. This experience is held above all others as a glimpse into the truth of the universe. Of course it is wonderful to glimpse into the truth of the universe. That is what we all do, all day and night, all the time.
There is no such thing as being spiritual in Church on Sundays, Synagog on Saturdays, Mosque on Fridays, or meditation on Thursdays, then being just regular when you are hanging out with friends or going to school or work. Your most delightful and insightful experiences are no more spiritual than your shallowest indulgences.
If you feel like there is some sort of spiritual worthiness in the world, then that is your world, day and night, in sickness and in health. You are that worthiness. The most spiritual moments are not generally blazing lights and trumpets, they are every single moment that there is. There is light everywhere and equal holiness in darkness. You can sing in the church choir, chant in the Zendo or yodel in the shower. It’s all just regular spiritual. Holy cow.
