Repent is, in the original Greek, "change your mind."
repentance can mean a reformation from within see Mt 3:8 bear, therefore, fruits worthy of the reformation, Young's Literal Translation
Young's Literal Translation Mt 3:1 ¶ And in those days cometh John the Baptist, proclaiming in the wilderness of Judea,
2 and saying, ‘Reform, for come nigh hath the reign of the heavens,’
3 for this is he who was spoken of by Isaiah the prophet, saying, ‘A voice of one crying in the wilderness, Prepare ye the way of the Lord, straight make ye His paths.’
4 And this John had his clothing of camel’s hair, and a girdle of skin round his loins, and his nourishment was locusts and honey of the field.
5 Then were going forth unto him Jerusalem, and all Judea, and all the region round about the Jordan,
6 and they were baptized in the Jordan by him, confessing their sins.
7 ¶ And having seen many of the Pharisees and Sadducees coming about his baptism, he said to them, ‘Brood of vipers! who did shew you to flee from the coming wrath?
8 bear, therefore, fruits worthy of the reformation,
Jesus himself knew the heart of men and he knew that the revolution must come from within because defilement comes from within
Mark 7:17 When he had entered a house away from the crowd, his disciples began to question him about respecting this illustration.18 So he said to them, "Are you thus without understanding also? Do you not perceive that whatever enters a man from outside cannot defile him, 19 because it does not enter his heart but his stomach, and then goes out into the sewer.” 20 And he said, "What comes out of a man, that defiles a man. 21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, 22 thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness. 23 All these evil things come from within and defile a man."
In Greek, two verbs are used in connection with repentance: me·ta·no·e´o and me·ta·me´lo·mai. The first is composed of me·ta´, meaning “after,” and no·e´o (related to nous, the mind, disposition, or moral consciousness), meaning “perceive, discern, mentally grasp, or be aware.” Hence, me·ta·no·e´o literally means afterknowing (in contrast to foreknowing) and signifies a change in one’s mind, attitude, or purpose. Me·ta·me´lo·mai, on the other hand, comes from me´lo, meaning “care for or have interest in.” The prefix me·ta´ (after) gives the verb the sense of ‘regretting’ (Mt 21:30; 2Co 7:8), or ‘repenting.’
Thus, repentance stresses the changed viewpoint or disposition, a rejecting of the past or intended course or action as undesirable. It is clear that the mission of John the baptist was to bring about a change of mind. The fundamental idea taught by the Scriptures is not that man must know sorrow, but rather that he must undergo a change, a change not merely of conduct but of the thinking and attitude.
Repentance means change of mind, transformation of the mind, change of thought and purpose.
A proper translation of the mission of John the baptist is: He came into all the region around the Jordan preaching submersion of reformation into a forgiveness of sins;
The Revolution of Consciousness is the FIFTH GOSPEL, we urgently need a radical, total and definitive change, and this is only possible through the Revolution of Consciousness. Intimate Self-Realization is only possible in isolated individuals with the help of adequate knowledge and methods. Such an intimate revolution can only occur within the individual and is in fact against the interests of Nature.
