While we can take a passive approach to experiencing, letting life happen as some say, aspirants work to co-create with experiences, seeing them as opportunities to develop.
We’ve mastered experiences when we’re no longer at the mercy of them.
This also means that we’re at different experience mastery levels; someone might’ve already mastered an experience you’re going through and vice versa.
Example: Let’s say on the busy trains in NYC, people are crunched together in the mornings and John Doe just can’t stand it. The thought of it moves him into anger, huffing and puffing, and this is the everyday travel. So John huffs and puffs in anger each day, which pumps cortisol throughout his body, dulling his mind, making him sick due to stress. This experience mastered John, because he doesn’t want to feel this way yet he does, repeatedly. Then John engages some kind of inner work practice, meditation, which helps him regain control over his response to the experience. Seeing the crowded train as a chance to practice patience, understanding (trains are always crowded in the morning, out of his control) and long-term vision (goal is to make it to NY on time), he transmutes the experience into a daily test.
The moment John Doe is no longer bothered by the experience, it’s mastered, and a new one will manifest.
