Four thoughts
Four thoughts (Tib. lodok namshyi; blo ldog rnam bzhi) - these are the four contemplations that turn the mind away from samsara, namely the difficulty of finding the freedoms and advantages and the impermanence of life, which turn the mind away from the concerns of this life. Reflections on the defects of samsara and on action (karma: cause and effect) turn the mind away from our attitudes and conduct with respect to future lives.
