I'm slowly going through Chogyam Trungpa's Training the Mind on the lojong training. I think it will be helpful if I put forth the points for discussion to help gain a better understanding, not only for myself but for anyone following along.
First, Train in the Preliminaries:
Reflect on and maintain an awareness of
1) The preciousness of human life and the conditions that allow one to learn and practice the buddhadharma
2) The reality of death, and that it can strike anytime
3) The entrapment of karma - that whatever you do, virtuous or otherwise, serves to further entrap you in the chain of cause and effect
4) The intensity and inevitability of dukkha yourself and all others
The short chapter then goes on to say that with these in mind, look to your guru (this is guru centric TB, IMO looking to the teachings in general is comparable) for the light leading you to a better way. It's about contrasting Samsara with Nirvana.
