This is the very thing which makes up the virtue of a happy person and a well flowing life—when the affairs of life are in every way tuned to the harmony between the individual divine spirit and the will of the Director of the universe.
  —Chrysippus, quoted in Diogenes Laertius
      Lives of the Eminent Philosophers, 7.1.88

(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.

    Chrysippus of Soli c. 279 – c. 206 BC was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of Cleanthes in the Stoic school. When Cleanthes died, around 230 BC, Chrysippus became the third head of the school. A prolific writer, Chrysippus expanded the fundamental doctrines of Zeno of Citium, the founder of the school, which earned him the title of Second Founder of Stoicism.
    Chrysippus excelled in logic, the theory of knowledge, ethics, and physics. He created an original system of propositional logic in order to better understand the workings of the universe and role of humanity within it. He adhered to a deterministic view of fate, but nevertheless sought a role for personal freedom in thought and action. Ethics, he thought, depended on understanding the nature of the universe, and he taught a therapy of extirpating the unruly passions which depress and crush the soul. He initiated the success of Stoicism as one of the most influential philosophical movements for centuries in the Greek and Roman world.
    Of his written works, none have survived except as fragments. Recently, segments of some of his works were discovered among the Herculaneum papyri.
