Mind IS an idea.
Concepts like birth and death are ideas... appearing as a language which is translated as knowledge appearing in the form of concepts which can only point one to their illusory nature. In the context there is no actual thing in the word thing. The word 'thing' is just an empty idea appearing full.
Only a concept can be KNOWN, and a concept has no experience of any life nor death...for reasons I've just explained above.
For every appearance and disappearance of what is known to be 'you' aka a concept...is sourced from what has ALWAYS EXISTED....else no appearance or disappearance would ever show OR become KNOWN
So that which has always existed cannot die, nor can that which has always existed live. The concepts 'live and die' are empty knowledge known that cannot be an experience, for the KNOWN know nothing.
Concepts known are of the mind as an idea, and even the mind itself is an idea.
Life and birth only exist in the realm of knowledge, the dream state, the illusory dream of separation, the realm of artificial knowledge.
If it is possible for a 'you' to exist at all .... then that 'you' must have ALWAYS EXISTED...for 'you' to be here now, 'you' must have always been here. How can 'you' NEVER not be here...'you' cannot experience your own absence or presence.
You are always and never not here. Only the concept of you is born and dies...NOT YOU...because there is no one other than YOU.
In other words..there is NO 'you' because there is no other than 'you'.
