Spirituality is not a “thing,” not an object that can be identified as something one possesses. It is a process, a growth experience. Ironically, when someone thinks he has achieved spirituality, he has probably lost it. One has it only as long as one is striving for it. Because we can never quite achieve perfection, we are always capable of improving ourselves. As long as we continue to improve ourselves along the lines we have discussed, we are spiritual. If we lose the momentum for growth and become stagnant, baser human inclinations toward gratification and comfort are certain to arise and work against the spiritual life. In spirituality, the searching is the finding, and the pursuit is the achievement.
– Rabbi Abraham J. Twerski
