Gautama Buddha's philosophy:
Follow the Noble Eightfold Path: right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.
To accomplish the Four Noble Truths: that suffering is an ingrained part of existence; that the origin of suffering is craving for sensuality, acquisition of identity, and annihilation; and that suffering can be ended!
Happy Buddha Purnima!
