Two Different Kinds of Energy ( St. Gregory of Sinai )

In every beginner two forms of energy are at work, each affecting the heart in a distinct way. The first comes from grace, the second from delusion. St. Mark the Ascetic corroborates this when he says that there is a spiritual energy and a satanic energy, and that the beginner cannot distinguish between them. These energies in their turn generate three kinds of fervor, the first prompted by grace, the second by delusion or sin, and the third by an excess of blood. This last relates to what St. Thalassios the Libyan calls the body's temperament, the balance and concord of which can be achieved by appropriate self-control.

ON DIVINE ENERGY

The energy of grace is the power of spiritual fire that fills the heart with joy and gladness, warms and purifies the soul, temporarily stills our provocative thoughts, and for a time suspends the body's impulsions. The signs and fruits that testify to its authenticity are tears, contrition, humility, self-control, silence, patience, self-effacement and similar qualities, all of which constitute undeniable evidence of its presence. 


ON DELUSION

  The energy of delusion is the passion for sin, inflaming the soul with thoughts of sensual pleasure and arousing phrenetic desire in the body for intercourse with other bodies. According to St. Diadochos it is entirely amorphous and disordered, inducing a mindless joy, presumption and confusion, accompanied by a mood of ill-defined sterile levity, and fomenting above all the soul's appetitive power with its sensuality. It nourishes itself on pleasure, aided and abetted by the insatiable belly; for through the belly it not only impregnates and enkindles our whole bodily temperament but also acts upon and inflames the soul, drawing it to itself so that little by little the disposition to self-indulgence expels all grace from the person thus possessed.
