Specifically the Quintessence of the Great Work.

So many of the old masters write about how to make the Quintessence
of Gold but then it appears they say very little about what to do with it.

Some talk about the Augmentation and whispers of accruing large quantities
of gold.

There is mention of a Great Medicine that can cure all diseases of the body.

Then there is the talk of longevity and the possibility of living for hundreds
of years.

Also hints of immortality.

But none of them write openly on how these things may be performed with
this Great Quintessence of Gold.

Is it the Quintessence that works these wonders or am I being misguided in
the way that I'm reading these old books ?

What can actually be accomplished with this Quintessence ?
