Here are a few quotes on that subject:
16:6.10 In the local universe mind bestowals, these three insights of the cosmic mind constitute the a priori assumptions which make it possible for man to function as a rational and self-conscious personality in the realms of science, philosophy, and religion. Stated otherwise, the recognition of the reality of these three manifestations of the Infinite is by a cosmic technique of self-revelation. Matter-energy is recognized by the mathematical logic of the senses; mind-reason intuitively knows its moral duty; spirit-faith (worship) is the religion of the reality of spiritual experience. These three basic factors in reflective thinking may be unified and co-ordinated in personality development, or they may become disproportionate and virtually unrelated in their respective functions. But when they become unified, they produce a strong character consisting in the correlation of a factual science, a moral philosophy, and a genuine religious experience. And it is these three cosmic intuitions that give objective validity, reality, to man’s experience in and with things, meanings, and values.
110:6.4 When the development of the intellectual nature proceeds faster than that of the spiritual, such a situation renders communication with the Thought Adjuster both difficult and dangerous. Likewise, overspiritual development tends to produce a fanatical and perverted interpretation of the spirit leadings of the divine indweller. Lack of spiritual capacity makes it very difficult to transmit to such a material intellect the spiritual truths resident in the higher superconsciousness. It is to the mind of perfect poise, housed in a body of clean habits, stabilized neural energies, and balanced chemical function—when the physical, mental, and spiritual powers are in triune harmony of development—that a maximum of light and truth can be imparted with a minimum of temporal danger or risk to the real welfare of such a being. By such a balanced growth does man ascend the circles of planetary progression one by one, from the seventh to the first.
149:4.3 He called attention to the fact that any virtue, if carried to extremes, may become a vice. Jesus always preached temperance and taught consistency – proportionate adjustment of life problems. He pointed out that overmuch sympathy and pity may degenerate into serious emotional instability; that enthusiasm may drive on into fanaticism. He discussed one of their former associates whose imagination had led him off into visionary and impractical undertakings. At the same time he warned them against the dangers of the dullness of overconservative mediocrity.
196:0.6 In a religious genius, strong spiritual faith so many times leads directly to disastrous fanaticism, to exaggeration of the religious ego, but it was not so with Jesus.
