-Poul Anderson, Operation Chaos (New York, 1995), p. 167.
Esoteric knowledge might mean either knowledge that is deliberately kept secret or knowledge that is only attainable at an advanced level of spiritual development. Mainstream Christianity is preached publicly without any doctrines held back and the Buddha has no "closed fist." I can tell you roughly how to practice "just sitting" meditation although I am not qualified to give instruction in it.
A practitioner in another Indian tradition was not allowed to describe his meditative techniques to me. I think that this is a precaution against corruption of the practices. Someone might hear indirectly about, e.g., mantras or visualizations, and think that he is practicing them while really getting them all wrong, then misleading others. John Blofeld, an expert in Tibetan Buddhism, wrote that anyone who claims to describe Tantric rituals should be disregarded because he is either breaking a confidence or lying.
