Chis book presents texts transmitted to the Temple of Humanity, an organization which was created in 1898 at the request and under the direction of Master Hilarion, one of the Masters of the Grand White Lodge. The Teachings of the Temple have become a guide in the fields of spirituality, science and philosophy. The lessons are published in the order in which the Masters transmitted them. In most cases, this order was the result of the needs that arose at the time. These lessons are therefore a source of truly extraordinary spiritual wealth and help.
