In plain words
Falling prey to the bad qualities that are the six inner enemies, desire, anger and the rest, failing to put to good use the station, the course, the understanding and the wealth that God has bestowed, falling prey to evil habits, turning wicked and coming to ruin, man falls and becomes lower than a beast. Instead, with time, karma, wealth, station and course, with a mind given to Dharma, with noble feelings, with steadfast dedication to God, with morality and honesty, to attain the divinity that stands higher than humanness: this is one path. To grow good saṅkalpas and share them with those around, to hold this to be man's chief Dharma, and to put every object to good use: that is the chief duty. To look at, all men are one; yet, as ‘Muṇḍe muṇḍe matirbhinnaḥ’ has it, each one's thoughts appear different, conduct different, words different. To bring these three into unity, to dwell on divinity and to make humanness fruitful: that, above all, is the chief duty of the mind.
The whole world is the very form of the mind!
As one's saṅkalpas are, so too are one's state and course! So man's good and bad rest on his saṅkalpas. These saṅkalpas are of two kinds. One is pure saṅkalpa; the second is impure saṅkalpa. Always searching out the faults of others, wishing others harm, tormenting others, handing sorrow to others, forgetting divinity, putting faith in impurity. To fit one's saṅkalpas into actions of this kind is the working of impure saṅkalpas. These impure saṅkalpas may look joyful at first. One's actions may look good. But later on they lead into great dangers. When we plan harm to others, it may harm the others to some extent; but it turns back and brings greater harm to the very one who planned it.
