55: The monads of the fourth Creative Hierarchy, the human Monads, exist in three main groups:
a. The Monads of Will.
b. The Monads of Love.
c. The Monads of Activity.
Mahachohan.  The officer in our planetary Hierarchy who presides over the activities carried on in the four minor rays and their synthesising third ray.  He has to do with civilisation, with the intellectual culture of the races, and with intelligent energy.  He is the head of all the Adepts.
Bodhisattva.  The exponent of second ray force, the Teacher of the Adepts of men and of Angels.  This office was originally held by the Buddha, but His place was taken (after His Illumination) by the Christ.  The work of the Bodhisattva is with the religions of the world, and with the spiritual Essence in Man.
The Manu.  The One Who presides over the evolution of the races.  He is the ideal man.  He has to work with the forms through which Spirit is to manifest; he destroys, and builds up again.  These three Individuals preside over the three Departments into which the Hierarchy is divided, and therefore represent in their particular sphere the three Aspects of divine manifestation.
