Do visual training exercises such as palming. For this, lie down on the floor with your elbows gently propped on a cushioned surface. Now place your palms over your closed eyes in a lateral fashion so that the fingers of one hand cross with those of the other. Do not apply pressure. In this state, you will witness a black field that will instill a state of relaxation in you. However, if you see a spectrum of colors or gray patches, you are in a tense state of mind. Visualize a happy memory with your eyes covered with your palms. Gradually, increase the time for this exercise.
