Conditioned life can have a certain momentum. When we talk about "letting go" and "surrender", it is about stopping this momentum, not being swept up in it without concern. It is important to understand that all conventional forms are arbitrary (although there are some biological imperatives), and aren't valid or holding some great moral superiority just because they are widely adopted. For example, if one were born into a world with completely different parameters (cultural, biological, etc.), then one would likely view those and their world much differently. To define the "box" precisely can be difficult, but in our current situation we can certainly identify signposts of this momentum that occupies attention (school, relationships, work, money, marriage, children etc.) Even the "eccentric", in so far as they are within the mental structures (even in opposition) are safely within this momentum. Most people allow this momentum (and the structures of it) to not only define them, but also dictate what is important to them. Many are so caught up in striving for what they "should" want, that they never actually examine what is truly important to them. Therefore, it can be instructive to take some time to just stop for a few moments, generate perspective, and examine what one truly wants and what is truly important. Of course, examining what one wants (desires) isn't ground breaking, since people pretty much do this all the time. However, most are doing this exercise while absorbed in life's momentum as defined by the paradigms of its structures. Therefore, a deep earnestness and honesty gained by perspective are required. Perspective is a function of wisdom, so if one doesn't have a certain wisdom, then it is meaningless to just instruct a person to generate perspective. Because of this, meditation on death is a very useful tool to both stopping momentum and getting perspective. One should view their life from their deathbed, and examine their life and what is important. If one is truly engrossed in the practice, then insight may take the form of regret (i.e. "i should have done this" or "i should have given more time/attention to that"). However, unlike in truly dying, in this practice, one may "reincarnate" and used the wisdom gleamed from that practice and apply it to their life. Even taking aside the more profound leaps, the practice can be useful in having a better quality life and removing some clutter. However, while death is a tool in this practice, when one continually allows oneself to "bump into it", it becomes a force and a genuine experience. This means that one experiences the death process while still living, and then not only is there perspective gained, but the fundamental nature of self, awareness, and manifestation are laid bare.
