The important thing is not so much that every child should be taught, as that every child should be given the wish to learn.
What parents inculcate in the child is permanently there because childhood is the most impressionable time of life.
Everything is the Supreme Being, which is Existence – consciousness - bliss, and ‘I am That’. By constantly cultivating this pure thought, get rid of impure thoughts. Then discarding even that thought and always inhering in the state of fullness, you will become the non-dual and undifferentiated Supreme Being and attain liberation.
In an evolutionary context, development has no end. That means we can always develop more, further, higher and deeper. In Traditional Enlightenment, it’s possible to become ‘fully enlightened’. In Buddhism, they call it ‘cessation’ or ‘the end of becoming’. Evolutionary Enlightenment is about infinite becoming for eternity.
