your spirit you have a wider range over someone who is limited to the mind.

All beings have a positive and negative nature. If we combine positive and negative correctly we produce light and with light you can see. Those who fail to do so will remain in darkness.

The spirit is a transmitter and the mind a receiver. What the mind does with what it receives depends on the discipline and control that you have over your mind.

If you're a negative being in this life knowledge will be the high of your learning, and you don't have to be good to learn knowledge. Wisdom is different. No negative being can be wise.
