“When passing on a spiritual tradition, therefore, we must be wary of the scholastic approach, sometimes misnamed ‘scientific’ or wissenschaftlisches, which, when employed in matters pertaining to the Spirit, is no more than one’s self-diffidence boosted by the authority of secondary sources. What matters is not my knowledge of what they say about mindfulness, but the fruit, which my own humble struggle to practice it, produces in me for my benefit and for the benefit of others.”
