Happiness or Unhappiness...

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
