Dr. Joe Dispenza emphasizes the importance of calming the mind and body before sleep in his evening meditation. He believes that this type of meditation can help you end your day with peace and achieve better sleep. In this meditation, you gently breathe and turn your attention inward. He suggests reflecting on positive feelings and good experiences from your day, which helps clear your mind of negative thoughts. This practice aids in entering a state of relaxation, allowing you to drift into deeper sleep.
