According to Vedic knowledge, one must hang on the walls only portraits of holy men. I look at so and become. If homes are surrounded by only the images of saints, the mood itself will be maintained in good condition, even if the impact of bad karma, and you will not say I have a bad mood. The mood is always good, because, according to Vedic knowledge, the mind has a subtle nature and always in contact with the fact that he was looking for. If you have an image of a holy man, say Sergius of Radonezh, if you are Christian tradition, St. Seraphim of Sarov, look, all at once will be a joy, purity of consciousness, because the contact will be with the Saints line. This is how the subtle body of mind. We look at something and contact.
