The final victory in the battle of life for every soul is when he has risen above the things which once he most valued.

Commentary by Hazrat Inayat Khan:

The final victory in the battle of life for every soul is when he has abandoned, which means when he has risen above, what once he valued most. For the value of everything exists for man only so long as he does not understand it. When he has fully understood, the value is lost, be it the lowest thing or the highest thing. It is like looking at the scenery on the stage and taking it for a palace. Such is the case with all things of the world; they seem important or precious when we need them or when we do not understand them; as soon as the veil which keeps man from understanding is lifted, then they are nothing.
Do not, therefore, be surprised at the renunciation of sages. Perhaps every person in the spiritual path must go through renunciation. It is not really throwing things away or disconnecting ourselves from friends; it is not taking things to heart as seriously as one naturally does by lack of understanding. No praise, no blame is valuable; no pain or pleasure is of any importance. Rise and fall are natural consequences, so are love and hatred; what does it matter if it be this or that? It matters so long as we do not understand. Renunciation is a bowl of poison no doubt, and only the brave will drink it; but in the end it alone proves to be nectar, and this bravery brings one the final victory.
