Psychology means soul knowledge, the study of the spirit.?

Psychology can be useful in spirituality. There is a saying in ancient scriptures that the mind is responsible for both man’s binding and his ultimate liberation from the cycle of birth-death or happiness-unhappiness. The personality defects in a person are responsible for unhappiness, whereas his qualities are responsible for happiness and contentment. The qualities or defects seen in an individual stem from the corresponding impressions of qualities or defects in his sub-conscious mind.

In order to lead a happy life and for effective spiritual practice it is essential that the personality defects in an individual are destroyed and qualities are imbibed or developed. Personality defects are the main obstacle in obtaining/experiencing happiness or contentment in one’s life. . Also they are the main obstacle in the efforts for attaining God, that is, in one’s spiritual practice. The more the personality defects, the more the mistakes in one’s individual and collective spiritual practice and the further away one is from the God. Hence, to avoid this, it is essential to remove personality defects.

it is the science of the mind in any of its aspects...That course at college was very difficult. The professor was over my head and i barely passed it..It sounded better than it was.

No, I wouldn't agree. The existence of a soul would have to established empirically before you would be able to determine whether or not psychology is or isn't able to recognize it.
