The most convincing expression of
the self-sacrifice for someone else would be the claim: ‘I am nothing else than
you’.
But the claim is logically impossible.
When you are nothing, your sacrifice does not matter. Then, when you pretend to
be or to live for somebody else, you deny the reality of the two distinct
bodies. Thus, you posit your sacrifice in a spiritual domain which does not
matter, too.
Therefore, the sexual love as one
of the strongest forms of love between humans indulges itself in many illogical
acts which involve the two partners. The detachment from those acts (especially
of sexual nature) may start the improper but logical investigation about the
value of the self-sacrifice. And nobody can see it at his or her partner.
[Since the relation between
parents and children does not benefit from the same great amount of illogical
acts, it is accordingly oftener affected by logical adversities which drive to
a total separation. They often begin by questioning the value of the mutual
sacrifice. It is a surprising separation, since it is a natural bound and thus
apparently stronger than sexual love.]
