There may be some conditions which make its life
possible. Thus everything is generated by the gathering
of some conditions. When it is destroyed, this is also
according to conditions. Thus the flower is born from
the seed, earth, water, sunshine, and is helped by the
gardener. If one of these conditions is lacking, the
flower could not exist. The conclusion, therefore, is that
nothing has a self. Non-ego is the truth of sunyata, and
its meaning. When one knows the nature of everything
as sunyata, one does not love or hate anything, because
both oneself and the objects formerly loved or hated are
sunyata.
In an uninterrupted time of meditation, one should
carefully think over this truth in samatha concentration.
Whenever it seems some realization of truth is
appearing and the flow of meditation seems to stop, one
should just clearly perceive it; do not think it over until
a delusion alien to the samapatti arises. If that happens,
bring the mind back to the truth again. If one's samatha
has been well developed, such an event will not happen
frequently. If it does, one has to leave off meditating
and perform some other good practice, such as worship
or confession, and try at a later time.

negatives surer and more elaborate, there are eight
negatives taught by the great saint Nagarjuna:
"No production, no extinction;
No annihilation, no permanence;
