the giver of Light recites a prayer that is believed to have a strong power to purify (the "Amatsu Norigoto Prayer"). The giver then holds his or her hand approximately 30 centimeters (12 inches) from the receiver's body. Sessions of Light usually last anywhere from 10 to 50 minutes. Sukyo Mahikari does not advocate the use of the art of True Light as a substitute for medical treatment or therapy. The founder of Mahikari, Mr. Kōtama Okada, taught that the purpose of the art of True Light is not to heal disease or illness, but to be of service to society, bring happiness to people, and attain divine nature. The art of True Light is said to purify the spiritual realm of one's home and society, making them more peaceful and harmonious. Thus, members are encouraged to radiate the Light to anything, anywhere, and at any time. Thus, the Light is not only radiated to human beings, but also to animals, food, buildings, and the natural environment. Universal principles Sukyo Mahikari teaches the concept of universal principles that, when practiced together with the Light, allow one to more quickly attain spiritual and personal growth. Sukyo Mahikari encourages people to incorporate the divine principles in their daily life by practicing virtues such as altruistic love, gratitude, humility and acceptance of the will of God. Members also practice prayer, cultivating positive and cheerful attitudes, promoting love and harmony, and helping others. Founder Kōtama Okada believed that if people lived in accordance with the universal principles, they would cultivate their spirituality, and naturally come to use science and technology that was integrated with an understanding of spirituality, to find solutions to pressing issues facing humanity. Other beliefs Sukyo Mahikari promotes the practice of yoko agriculture. The practice of yoko agriculture involves organic agriculture combined with the use of positive words and attitudes to help people to cultivate respect for nature and restore soil to its pure and fertile condition. Accordingly, respect for nature and the natural environment is encouraged. The arbitrary use of chemical fertilizers, without consideration for the local environment, is discouraged. The organization has helped to create natural farms and promotes the distribution of natural and organic produce throughout the world.
