All dreams have disappeared.
All duality is of mind. It is mind that separates things, it is mind that defines. So this too cannot be perfect enlightenment.
In the Jaina concept only one remains, the soul. This is far better -- better than Christianity, better than Hinduism. The Hindu idea is a little better. Only two remain: the God and the soul. Better than three, but still the two, the duality. Only one remains, the soul. But Buddha says that too is not perfect enlightenment, because to think of one, it will be necessary to think of two and three and four and five. Just to say 'one' is enough to bring in the whole train. The one cannot be defined without bringing the two in.
What will you mean by 'one'? You will have to say not two. So the one will need the other at least for its definition. The other will remain somewhere hidden it has not disappeared completely. If I am there, then you will be there. It cannot disappear completely. The 'I' will need the 'you'; just for its own sheer existence the 'you' will be needed. 'I' exists only in the pair with 'thou'. They are together:; I-thou is one reality.
So Buddha says 'I' has also to disappear. Then the whole trinity is gone. In the ultimate experience there are neither three nor two nor one. It is pure sky -- nothingness, no being, no entity. It is zero, SHUNYATA. That's why Buddha says this is:
'... UTMOST, RIGHT AND PERFECT ENLIGHTENMENT.
FURTHERMORE, SUBHUTI,
SELF-IDENTICAL IS THAT DHAMMA,
AND NOTHING IS THEREIN AT VARIANCE.
THEREFORE IS IT CALLED
UTMOST, RIGHT AND PERFECT ENLIGHTENMENT.
SELF-IDENTICAL THROUGH THE ABSENCE OF A SELF,
A BEING,
A SOUL,
OR A PERSON....'

All forms have disappeared. That's why the sky remains identical with itself. There are no longer any forms arising, disappearing, no longer any change, no movement. All dreams have disappeared.
