The process of achieving jhana, or deep states of meditation, is not something that can be hurried or forced. It’s essential to acknowledge that any setbacks you experience are actually part of your journey toward success. When your attempts to reach these states don't meet your expectations, it's important to practice mindfulness and observe the feelings of frustration that arise. This practice helps you build your mindfulness skills and brings you closer to your goal.
The key takeaway is that persistence is crucial. As long as you continue your practice without giving up, you remain on the path to achieving jhana. Remember, every step and experience, even the difficult ones, contribute to your growth in meditation. By maintaining your commitment, you can overcome challenges and keep progressing toward deeper meditation states.
