To answer the question of how to let go when manifesting, I want to bring up an important point: manifestation is happening when you take action. So letting go does not mean this is a set-and-forget thing. Letting go means that you overcome the manifestation blocks that are in your way and that you get vibrational aligned with your goals. What helps manifestation to come true easier is not that you try with all means to let go of your goals, but to let go of old limiting beliefs, habits, and self-image. This is a personal growth journey that takes time.
