Do you experience yourself as a person with capacities as compared to someone who can do particular things in particular situations?
I see 'myself' as a no-self - just a bunch of physical and mental processes. I don't know. Things get done.
Do you have good days and bad days, where you're more "on" and "off"? Do you know what internal or external conditions determine this?
Some days flow more easily than others. Of what combination of circumstances promotes this I have no idea.
(How much) do you feel "at choice" with respect to this?
No choice. No-self = no free will.
Do you believe it's possible to cultivate yourself and your capacities? If so, how? What are the most important ways you do this? Do you have some rituals or practices, or other things you do that help or support you in this?
Abilities and capacities will be exercised. You can't stop it from happening.
What are some specific capacities you are aware of, and what do you know or believe about how they function in you or in other people?
Awareness of a capacity is just finding things easy that others might find difficult.
Do you have a sense of your own strengths and weaknesses?
Strengths and weaknesses are a result of genetics and our experiences in life.
Suppose we take this area of your experience, and use the label capacity or ability to refer to it. What area(s) of life do you focus on -- or give attention to -- where you're growing or challenged in a positive way? Do you have specific intentions and aspirations?
Do you have goals or intentions about the quality of Being (presence, creativity, intelligence) that you experience and bring into play? How is this expressed in action?
How do you know whether these capacities are present to a greater or lesser degree? How do you discriminate which way is "up"? Whether something you're doing is having a positive effect?
How does this skillful or effective knowing work in specific situations? Perhaps some of the following questions will be evocative.
