According to the readiness of its tool, the soul experiences and knows life. It is the condition of the mind which enables the soul to see life clearly. The mind can be likened to water; when the water is troubled there is no reflection to be seen; when the water is clear then it shows the reflection. But in the pursuit of material gain, which is what he values most, man has become absorbed in that kind of life and has lost the benefit of life; as it is said in the Bible, "Where your treasure is, there will your heart be also."
