Answer: It does not require much time since spirituality isn’t measured by years but actually depends only on our desire. We can “wait for the eggs to hatch” like chickens and not attain anything, or we can jump and leap above all these actions in a minute. It all depends on our desire.
The desire develops between us to the degree that we show each other what we want and spur different feelings such as hate, envy, and competition in each other. These are very useful.
