The kingdom of heaven

The kingdom of heaven is in the hearts of those who realize God.

Bowl of Saki, September 25, by Hazrat Inayat Khan

Commentary by Hazrat Inayat Khan:

Being born again means that the soul is awakened after having come on
earth, and entering the kingdom of heaven means that this world, the same
kingdom in which we are standing just now, turns into heaven as soon as the
point of view has changed. Is it not interesting and most wonderful to
think that the same earth we walk on is earth to one person and heaven to
another? And it is still more interesting to notice that it is we who
change it; we change it from earth into heaven, or we change it otherwise.
This change comes not by study, nor by anything else, but only by the
changing of our point of view.

The difference between a scientist and a mystic is that the former analyzes
the things he is interested in, studying them by different methods in order
to ascertain as much information about them as he can, the ways in which
they can be of any benefit, their uses, and their nature, whereas the
mystic, though in a way doing the same, first aims at lighting that light
within himself by which he can see in this world of darkness and illusion,
instead of using some technical instrument or special scientific process.
As it is said, ‘Seek ye first the kingdom of heaven’, so his first task is
to light the candle within.

The Kingdom of Heaven is in the hearts of those who realize God. This is
recognized in the East, and great respect and regard is always shown for
the holy ones. … Speaking from a metaphysical point of view, the Kingdom
of Heaven may be attained by the way of repentance. If we have offended a
friend, and he turns away from us, and we in fullness of heart ask for
forgiveness, his heart will melt towards us. If, on the other hand, we
close our heart, it becomes frozen. … When by warmth of heart we can
break our limited self, we merge in the One, the unlimited. When our
limited kingdom is lost from our sight, we inherit the Kingdom of God.

The basis of mysticism is to be found in that saying of the Bible, ‘Seek ye
first the kingdom of heaven, and all these things will be added unto you.’
Thus the search of the mystic is for that kingdom, for God, and in that
search what does he find? In the search for God he finds himself.
