Destiny is what we are making ...

By our thoughts we have prepared for ourselves the happiness or
unhappiness we experience.

Bowl of Saki, by Hazrat Inayat Khan

Commentary by Pir-o-Murshid Inayat Khan:

Fighting with another makes war, but struggling with one's self
brings peace.

All our possessions, all that we collect in life, all these things
which we shall have to leave one day are transitory; but that which
we have created in our thought, in our mind, that lives. A person
thinks, 'Some day I should like to build a factory.' At this time he
has no money, no knowledge, no capability; but a thought came, 'Some
day I should like to build a factory.' Then he thinks of something
else. Perhaps years pass, but that thought has been working
constantly through a thousand minds, and a thousand sources prepare
for him that which he once desired. If we could look back to all we
have thought of at different times, we would find that the line of
fate or destiny, Kismet as it is called in the East, is formed by our
thought. Thoughts have prepared for us that happiness or unhappiness
which we experience. The whole of mysticism is founded on this.

Joy, sorrow, love, all depend on our thought, on the activity of our
mind. If we are depressed, if we are in despair, it is still the work
of our mind; our mind has prepared that for us. If we are joyful and
happy, and all things are pleasant, that also has been prepared for
us by our mind. It is only when our mind works without control that
unhappiness, sorrow, trouble, pain, or whatever we experience comes
without our intention. No one could wish to create hell for himself;
all would create heaven for themselves if they could; and yet how
many allow their minds to create these things for them, regardless of
their own intention.

'The present is the reflection of the past, and the future is the re-
echo of the present.' Destiny is not what is already made. Destiny is
what we are making. Very often fatalists think that we are in the
hands of destiny, driven in whatever direction in life destiny wills;
but in point of fact we are the masters of our destiny, especially
from the moment we begin to realize this fact. ... Man is responsible
for his success and failure, for his rise and fall. And it is man who
brings these about either knowingly or unknowingly.
