Gautama is the primary figure in Buddhism, also commonly refered to as Buddha ‘The Awakened One’. This verse talks about following the path which leads to peace of mind, to the higher wisdom, to full enlightenment.
Passage
What is that middle path, O Bhikkhus, avoiding these two extremes, discovered by the Tathagata–that path which opens the eyes, and bestows understanding, which ‘leads to peace of mind, to the higher wisdom, to full enlightenment, to Nirvana? Verily! it is this noble eightfold path that is to say
‘Right views;
Right aspirations;
Right speech;
Right conduct;
Right livelihood;
Right effort;
Right mindfulness;
and Right contemplation.
‘This, O Bhikkhus, is that middle path, avoiding these two extremes, discovered by the Tathagata–that path which opens the eyes, and bestows understanding, which leads to peace of mind, to the higher wisdom, to full enlightenment, to Nirvana!
