The world of our thoughts is the seedbed of our actions and deeds.
Whatever will grow from this seedbed depends largely on how we cultivate our thoughts.
It would be unrealistic to expect our egocentricity to change its own position by itself. For it is our ego who turns deaf when it is required to free himself from self-interest. It likes to be blind when it is asked to look around the neighbor's house and see if it can make itself useful there.
We prefer to remain unmolested by the concerns of others. We love to make ourselves comfortable in our own house, to treat ourselves to everything we can get hold of.
This limited view makes our thinking sluggish and comfortable.
