The thing to abandon is the habit of looking out for self- interest only. Fail to stop this and continue to do everything with only self-benefit in mind, we will forever be barred from the realm of Mahayana and remain an outsider regardless of how our actions are classified, mundane or supramundane. Although we may think of ourselves as Mahayana or Vajrayana practitioners, we in fact have not even set foot on the right track of Mahayana practice, much less that of Vajrayana, if the motivation stays selfish. For this reason, selfishness must be forsaken.
