In addition, you O my son, avail of your youth and live in the remembrance of Him, the Sublime and Exalted, the love of Him and in conformity with your primordial nature. The remembrance of the Beloved is in no way clashes with political and social activities or serving the religion and God’s servants. In fact, this remembrance helps you in traversing His path. However, beware that the temptations of the carnal self and inward and outward evils are great in number. It may happen that these temptations dissuade man from remembrance of God in the names of God and in the name of serving the people of God, driving man towards himself and his desires.
Taking care of the self is among the stations of spiritual wayfarers in distinguishing the path of egoism and theism. May God grant you and us success in observing these stations! Many a time the inner Satan will tempt us, the old ones, in a way and you, young people, in a different way.
