Meditation can bring up all sorts of experiences, like those black dots some people notice. It's important not to cling to these moments too tightly, whether they feel good or bad.
Acceptance and gratitude for whatever arises can make your practice much richer! Instead of expecting specific experiences, such as those dots, try to focus on the act of meditating itself.
Remember, there’s no such thing as a bad meditation session. Each moment is just part of your journey, and every experience contributes to your growth. Enjoy the ride!
