Different views of the self (ego) from different religions:
Wrong self view of Nihilism
Wrong self view of Eternalism
Right self view of Buddhism preached by Buddha. The self is very difficult to realize because the self is complicated as the diagram says. Form, feeling, perception, volition and consciousness are elements of the five aggregates. The Heart Sutra said "The five aggregates are empty (void)." therefore the self are empty.
The known, known unknown, unknown unknown of all dharmas (phenomenons) in the universe. Animals and unlearned & uncultivated human beings know 'The Known'; buddhist Monks, buddhist Sages, Gods, Noble spirits know 'The Known Unknown'; Bodhisattvas, Pakecca Buddhas and Buddhas know 'The Unknown Unknown'.
'Awakening' is the first step only, the second step and most important of 'Buddhism is all about' is Buddhist practice and Buddhist cultivation. Practice is practicing meditation and practicing Pure Land Buddhism. Cultivation is cultivating your mind therefore also cultivating your mouth and your body.
