There is several ways to die moment by moment. Wisdom can help us to transform impressions. You can practice non-identification or sacrifice your ego. Learning how to pay attention robs the ego of its food. But to truely understand the ego requires the awakening of consciousness. For this you need to find a genuine teacher who can show you how to crystallize the observer within you. This practice however can be done moment by moment without the need to sit down and awaken consciousness each time. These are all just tools that we can use in any given moment.
