Messages in wisdom - Al-Ghazali

Advice is easy, and the problem is accepting it; because in the taste of the follower of desire it is bitter. Live as you wish, for you are dead. Love whom you wish, for you will part from him. Do what you wish, for you will be rewarded for it. Know that the key to knowing Allah the Almighty is knowing the self. *** This book contains four wonderful messages written by the proof of Islam Imam Abu Hamid Al-Ghazali, who died in 505 AH, which are "O Son," "The Path of the Gnostics," "The Chemistry of Happiness," and "The Advisory Message."
