To strengthen your psychic senses, you must practice sitting in the power, which is another way of saying, becoming more spiritual.
Sitting in the power is a visual exercise where you find a quiet place to sit, close your eyes and take yourself on a visual journey. Imagine a bright white light all around you, even covering your body. When you slowly inhale, the light gets bigger and when you exhale, it gets brighter. As you do this the light engulfs your entire room, then the house, and then the outer space. Then you take another breath and come back to your awareness. At this point open your eyes and take a sip of water. If you do this a couple times a week, you will be building on your own spiritual growth and awareness.
Many Blessings.
