The method to treat neurasthenia: During meditation or when calming down, recite the Heart Sutra or the Medicine Buddha Mantra very slowly. While reciting, visualize golden Buddha light shining upon the head, especially the back of the head, continuously flowing into the head or the back of the head. Simultaneously, visualize black or gray karmic obstacles continuously being expelled from the top of the head. Continue this practice until sleep improves and no black energy can be visualized anymore, at which point the visualization is no longer necessary. The stronger the concentration power, the more effective this method becomes. For those with relatively strong concentration, this method is highly effective; it simultaneously strengthens concentration power and enables one to attain deep concentration quickly. Visualize the golden Buddha light entering from all directions above the head—directly or at an angle—both are acceptable. The stronger the concentration, the broader the scope of visualization, which also rapidly enhances concentration power. You may imagine it in whatever way feels most convenient. For illnesses in other parts of the body, apply the same method of visualization. This visualization can also be done for others, but doing so requires bearing their karmic obstacles.
