Like yin and yang, why does one need the other to exist? If you know astrology answer this... How is Libra and Pisces the same, how are they different, just curious... If you know any other opposites and have questions on it, ask away...
We have opposites because we are on a 3 dimensional planet. We are experiencing a 3D reality, which is a duality. If you noticed though lately, that people are breaking free from this duality. The consciousness is rising and people are realizing that love an peace is the only way. As we embrace more and more of the energies around us we will continue to rose in consciousness and we will eventually break free from this duality. It won't be long my friend, it won't be long... - peace, joy, love, and light
The opposites are there so you can feel the other more strongly and to give meaning to each other. I don't know anything about those signs, they're not in my chart
What I realized about love is like when you find the one you love, I've discovered that I'm yang, and she's yin. This is the oneness and selflessness one realizes through love. We complete each other. Then I realize we are essentially one in the same. It is just how nature is. There really isn't a why, other than to possibly have balance.
Opposites are generally part of the same whole, it only matters where you draw the distinction between the two. Take 'beautiful' and ugly' for instance.
Some interesting points, although I've always thought as love, coming from yang, then lust coming from yin. Just something I always associated in mind with. whats your thoughts on that?
