Answer this question to the best of your ability:
What sensations should a meditator expect to experience during Access Concentration?
During Access Concentration, a meditator can expect to experience intense focus on the breath as it moves with the body. As they progress, they may start noticing new and surprising sensations beyond what should be expected with the breath. Common additions are tingles and vibrations, which can sometimes be quite energetic indeed, as waves or even a flood of energy running through the body. These sensations, known as Piti (sense of energy) and Sukha (sense of joy, non-sensual pleasure), may arise in various combinations and intensities, and are a natural part of the meditation process at this level.
