This is known as “absent treatment” also. You can transmit Prana through space to your friend who is living at a distance.
You can fix specific appointment hours through correspondence. For example:
“Get ready at 8 p.m. Have a receptive mental attitude. Lie down comfortably. Close your eyes. I shall transmit my Prana.”
At the fixed hour, sit quietly. Practice Pranayama and concentrate deeply. Visualize the person clearly in your mind. Imagine that Pranic energy is flowing from you through space into the patient’s body.
Through strong concentration, faith, and will-power, Prana travels across space like radio waves. The patient receives warmth, relief, and healing energy.
