You could look to the idea of making something sacred as
being one of the core concepts of sacrifice. But what
does it mean to make something sacred? Maybe
everything is already sacred and it takes higher awareness
to perceive it as such.
I agree with the essence of renunciation being about how one
chooses and focuses upon aligning oneself with one's truer
Self and therefore acting for the transcendent good (the
Higher Self), thereby detaching from solely personal desires
(aka selfishness). I think the individual would consider it
a sacrifice of the material/mental for the spiritual.
One of my favorite Gita passages is Chapter 6 from the WQ
Judge recension, which is a little different from the text
provided here (for the same passage): “He should raise
the self by the Self; let him not suffer the Self to be
lowered; for Self is the friend of self, and, in like
manner, self is its own enemy.” (It uses
capitalization to distinguish between higher and lower
I think renunciation or sacrifice stem from having the faith
that as I give up that which is precious or desirous to
'me', a space will be created which wasn't there before
which has now the capacity to be infused with something not
of my desire.
I think there is a great wisdom in renunciation and sacrifice. Its as if
the elders and wisemen of old knew that most beings will be faced with
countless distractions and materialist desires, that only through
renouncing will be capable of remaining pure.
