Dana, Sila, Samadhi, Pagngna
Dana & Sila practices generate thoughts, (Punya Karma, in Pali), that would create well-being within Samsara. One to give away things, which oneself earned through hard effort might know an easy task. In order to complete Dana Punya Karma, one has to give Alms without a thought of any return.
Observing Sila, or Shiksha, requires much more effort than Dana. Sila is also a Punya Karma, however, basic discipline in oneself would create a powerful platform for such person to attain Nirvana.
The Buddha said: "One who knows that oneself is not breaking these five root disciplines, shall not fear to live anywhere"
