Q: When I first started meditating I had an intense desire for liberation. This period lasted for 3 - 4 years. In the last twelve months my enthusiasm has been slipping. I now seem to be more and more content with my worldly life.

The satisfaction which comes from the outside world is transient. At death it will all be lost. Human life is given to you for the sole purpose of realising the Self. If you die without realising the Self your life has been wasted. Death can come at any time. I am telling you this so that you will become aware of your own death. If you are constantly aware of the possibility that you may die at any moment, your enthusiasm will increase. Try to cultivate this awareness and see if it makes any difference to your sadhana.
