Definition:

1. Some things are up to us, while other things are not.

Examples:

1. In our control - decisions and behaviours (provided we are mentally healthy); not in our control - circumstances and other people's thoughts and actions.

Insights:

1. Most things are not really in our control.
2. Death is not under our control, but how we think about death is under our control.
3. We can make choices, select goals, and strategies but we cannot determine the results or other factors that might reveal themselves.

Principles:

1. Practice non-attachment to things and people.
2. Be concerned with what is under your control, treat everything else with composure.
