We are not always aware of the powers we have. Depending on the disposition of our heart we can transmit either good or evil, Elder Porphyrios advises us. He warns us to be very careful to see things with a positive view.
He says,
Even the slightest anger or indignation does harm. We need to have goodness and love in our soul and to transmit these things.
We need to be careful not to harbor any resentment against those who harm us, but rather to pray for them with love… We need always to have thoughts of love and always to think good of others. He highlights for us the example of Saint Stephen. As he was being stoned to death he prayed, “Lord do not hold this sin against them.” How many of us can do this? Not many, but this is our potential with the love of God filling our mind at all times. Grace flows at these times enabling us to act in saintly ways. Saint Stephen had this love of Christ in his mind and heart as he was being stoned. He sets an example for us to follow.
If we pray with love for others this is also transmitted. It is important to be in touch with this invisible power of our soul. In both good and bad, this power is transmitted over great distances.
He says,
If we pray with love for someone, whatever the distance that separates us, the good is transmitted. So distances do not affect the power of good and evil. We can transmit these across boundless distances. This is not something Elder Porphyrios is talking about in any theoretical way. After he became a monk he was given though God’s grace the powers of clairvoyance. In his autobiography he recounts a story of seeing his elders returning when they were on the other side of the mountain. He could visualize water under the ground when seeking a well for his monastery. One of his spiritual children, Constantine Yiannitsiotis, recounts how he saw in both people and things the cause of events. In his book, With Elder Porphyrios, he offers many examples of these powers in action. He understood the past as well as the future.
The person who receives this gift of clairvoyance is one who loves God as Elder Porphyrios does. Such power is an act of divine grace. The Elder gives us the preconditions for this.
He says,
Only a person who has humility receives these gifts from God; he attributes them to God and he uses them for His glory. The good, humble, devout man who loves God, deluded or led astray. He feels in his heart that he is truly unworthy, and that all those things are given to him so that he may become good, and for that reason he makes his ascetic struggle. Our aim must be to become holy and God may then grant us additional powers. Grace does not come to those who are ego-centered. It comes only to those who are humble, selfless, and love God above all else.
