Thou hast asked about the statement in the Hidden Words: "O Son of Spirit! Turn thy sight unto thyself that thou mayest find Me standing within thee, mighty, powerful and self-subsisting." [Arabic no. 13] This is the same statement as was made by Christ to His apostles in the Gospel: "The Father is in the Son, and the Son is in you.”(John 14:20)
It is evident that, when a heart is purified and through divine education and heavenly teachings becometh a manifestor of infinite bounty, it is like a clear mirror. The Sun of Truth will be reflected in it with might, power and omnipotence, to such an extent that whatever is brought before it is ignited and consumed. This is a brief interpretation because of lack of time. Therefore, do thou reflect and meditate upon it so that the doors of inner meanings may be opened before thine eyes.
