The more spiritually developed the person carrying out the blessings or the healing practices, the more powerful is the healing result or potential. These pills often contain the relics of previous great meditators and saints, bestowing much power on the pills. Many Tibetan lamas actually blow on the affected part of the body to effect healing or pain relief. I have seen a person with AIDS with intense leg pain have his pain disappear after a lama meditated intensely and blew on his leg for twenty minutes. Compassion is the power that heals.
Visualisation can also be very powerful healing.
One method is to visualise a ball of white light above your head, with the light spreading in all directions. Imagine the light spreading through your body, completely dissolving away all sickness and problems. Concentrate on the image of your body as completely healed and in the nature of light. This type of meditation is even more powerful when combined with visualising holy images and reciting mantras. I often tell my Christian patients to visualise the light as Jesus, with the light emanating from him.
