The basics teachings of Buddha are about understanding what we are, who we are, why we are. When we begin to realize what we are, who we are, why we are, then we begin to realize what we are not, who we are not, why we are not. We begin to realize that we don't have basic, substantial, solid, fundamental ground that we can exert anymore. We begin to realize that our ideas of security and our concept of freedom have been purely phantom experiences.
Chogyam TrungpaWalking the spiritual path properly is a very subtle process; it is not something to jump into naively. There are numerous sidetracks which leades to a distorted, ego-centered version of spirituality; we can deceive ourselves into thinking we are developing spiritually when instead we are strengthening our egocentricity through spiritual techniques. This fundamental distortion may be referred to as spiritual materialism
Chogyam TrungpaThere is no promise of love and light or visions of any kind - no angels, no devils. Nothing happens: it is absolutely boring. Sometimes you feel silly. One often asks the question, "Who is kidding whom? Am I on to something or not?" You are not on to something. Traveling the path means you get off everything, there is no place to perch. Sit and feel your breath, be with it.
