Thou hast asked about the statement in the Hidden Words[no.13]:
"O Son of Spirit! Turn thy sight unto thyself that thou mayest find Me
standing within thee, mighty, powerful and self-subsisting." 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."1
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. ('Abdu'l-Bahá, from a Tablet to an
