Let Experience Be Your Guru
It’s a statement attributed to the Buddha, Siddhartha Guatama, from ages ago, but it’s not a statement worth repeating because it was made by the Buddha or because it’s ages old. The idea is that people should not follow teachers of wisdom, but should instead cultivate their own wisdom.
Listen to others, by all means, but test every assertion made by leaders, and if their assertions don’t match reality, don’t follow the paths they have cleared. Go your own way, and trust your own skeptical mind.
It’s a pre-modern version of the popular aphorism, question authority, written within the outline of the meditating heretic of Hinduism.
