There can be no - and I mean NO, none at all - love unless it is completely unconditional and non-judgmental. For that matter there can be NO relationship if there are any kind of constraints of the my-way-is-the-best-way, what-I-know-is the-only-thing-worth-knowing, I-cannot-see-what-you-mean-so-it's-rubbish, or, just-accept-what-I-say variety. Even the teeniest-weeniest self-wiping, for-the-sake-of-peace constraint puts pressure on a relationship.
By relationships I mean, all kinds - very close, close, not-so-close, or distant. For those we come across, but do not think of in terms of a relationship, or who are not part of the circle we move in, charity (read good will, compassion) substitutes love.
People are what they are (and I include children as well) because of their experiences, thoughts, life processes, reactions, food & drink, economic compulsions, climate, and possibly even karma. How then can we pass judgment on them, or put conditions on our interactions?
If we cannot love, or be charitable, the best thing to do would be to move away from that person/place/happening, till we get a better perspective...
This is not to condone the I-am-like-this-only attitude. Simply because, we-are-not-like-that-only. Being non-judgmental would make us review ourselves, so that we can be better persons, acquire what it takes, and tweak off the jagged edges. Maybe there is someone out there who needs a prop, or an affirmation of who they are...And when we do, we would add to the universal consciousness rather than subtract from it.
Universal consciousness sounds high-falutin'. In fact it is not. It is just the collective energy of all mankind...Ideally, this needs to be positive...
