Meditation and heartbeat

Your phenomenon is not called premature beats. During meditation, people who can generally settle down initially will fall into a comfortable state, that is, they will fall into a faint peace, just like being slightly sleepy. But if there is any noise or interference from the outside at this time, they will wake up immediately, that is, they will get out of that state, and their hearts will accelerate because of fright. Bend over later, in fact, you are already asleep at this time. When you fall asleep, your posture will get out of control and your waist will bend. Both prove that your method is wrong. You should never think of meditation as relaxing sleep. Of course, this is also a common mistake made by beginners. True meditation will indeed enter a quiet realm at first, but it will go deep into the realm of meditation. People are awake, and their energy is in a virtuous circle, increasing constantly. This is a state of enjoyment, which cannot be described. You must have the right way to clear your mind and meditate. The effect of lethargy is of little use.
