Our underlying nature is fearlessness - having nothing to defend, being nothing vulnerable. How can we offer others this peace?
Is sacredness something real? What is holy in a person, place or object? Can we find this in the pragmatic and experiential sphere of Dharma?
Insight is itself a not-self not-other experience... a not-self not-other gratefulness experience is a natural response.
"Whatever is subject to arising is subject to ceasing" - how is this a revelation of the Deathless?
Is praying a denial of karma? Results without a cause?
What is, and what is not, enlightenment? Don't get off at the wrong stop!
What can we know about death - before doing it?
What is death not the end of?
Be careful about equating the ability to calm thinking with being a Buddhist master. How much freedom from thinking do we need, to reach the jewel of understanding which then makes thinking not a problem? We could spend years manipulating our mind into thought-free states unnecessarily.
In our own lives we can easily find things we thought were true which we subsequently think not to be true. So our pursuit of the truth about self can not depend upon thinking. We need another way of knowing, one more direct than our thinking.
