We cannot express gratitude
This Holy month of Ramadhan, with all of the blessings that it has, we cannot express gratitude for even a single blessing. However, if in this Holy month of Ramadhan that just passed us, if we developed a spiritual state, we should try to preserve it until the next month of Ramadhan. And if a renewed spiritual state did not develop, we should be disappointed and try to develop one.
These spiritual highs and commotion are all fleeting; they will all come to an end. That which is before us is what lasts and really remains with us, and hence, we must try to rectify our inner selves.
Imam Khomeini
