A tradition of the Prophet of Islam tells us that ‘Simplicity is a part of faith’. Simple living means living according to little needs, not unlimited greed. Simple living is a safeguard from all kinds of distractions. It saves time, energy, money, and other resources, which can be used to develop. Therefore, simple living is a crucial principle for a successful life. So, simple living is the only sensible way of living. All other ways of living are simply disastrous. High thinking means thinking beyond one’s desires, transcending surroundings, and immediate attractions. It makes a person wise and safeguards one from going astray in the jungle of trivialities. Then they can think about the severe issues of life and death. The most outstanding achievement in this world is intellectual development. The Creator has blessed us with a mind with unlimited potential. It is for us to unfold this potential of our mind, to turn this potential into actuality. The target Islam gives us is to develop our mind or intellectual development. The mind can be developed through study, intellectual exchange on serious matters, and thinking and contemplation. In the short period that we have in this world, we cannot afford to waste ourselves on matters other than intellectual development. Simple living and high thinking help one attain success in this world and the next, after death.
