Kia Ora Bailey,
Many thanks for your response, that is, how you see things regarding "unconditional love" It's very thought provoking[not that I need my thoughts provoked]
My reply is somewhat generic:
You make some valid and interesting points, regarding this psycho-physical phenomenon we label the human being[I also like the Zen and Taoism bit at the end of your post
"like the word Zen is not Zen, like the Tao that can be named is not the eternal Tao!"]..
However unconditional love will for some go way beyond scientific understanding and into the realms of ones personal 'spiritual' understanding/belief...In other words beyond the mundane intellect of science and biology and into the workings of the all-encompassing 'mind'
In Buddhism the mind is viewed as a non-physical phenomenon which perceives, thinks, recognises, experiences and reacts to the environment.
There are two main aspects of the mind they are clarity and knowing; the mind is formless clear, and allows for objects to arise in it, and it is the knowing, the awareness,/consciousness which can engage with objects.
And from a Buddhist perspective, unconditional love requires the practice of non-attachment, that is non attachment from self-centred motivations, meaning Buddhist compassion involves detached and disinterested affection, but this does not mean lack of empathy towards others..
It is a self-less expression of care, which refer to one striving to destroy the attachment to the 'self'-illusion. By transcending all "conditional" loves, This comes about by changing ones behaviour and 'thinking' hence taming and re-programming the mind...
Unconditional love involves non-attachment because there can be no self-centred motivation in a life of true love. Hence if one can achieve this then one has reached "Buddha Nature"
However this is just how many involved in Buddhism views "unconditional" love...Much is in agreement with your finding Bailey..
So in a nutshell :
"Buddhist philosophy teaches that true love is free from attachment and emotional dependence. Love is unconditional, the need of reciprocity is mere passion! The greatest lesson of Buddhism is that detachment does not mean that loving is meaningless. Rather, detachment is the state of mind that allows people to love even more, abundantly, and for the right reasons – because every single living being is a small part of the same universal body and not loving the neighbour would be the same as not loving oneself.!"In the mundane "conditioned" world in which we live, it's true when we use the term "unconditional love" it may not fit with the Buddhist interpretation, however how a person chooses to interpret "unconditional love" can not be dismissed, it's 'real' for the beholder of these thoughts and feelings ...
