Doesn't marriage seem a bit old fashioned, a bit dated - not to mention self-limiting?
We think that by dedicating ourselves to one 'external' person (i.e. not ourselves) we are expressing our love for them. But is it love? Is it a form of attachment? Clingyness? Possessiveness? Obsessiveness? Are you clinging to the person 'you love' and acting like a parasite? Not giving them space - not letting them live their lives. Many people are unaware they do this and think it is love.
Eckhart Tolle's right when he says, 'True love has not wanting'.
'God is love' it says in the Upanishads.
If anything, when we say we love someone, the majority of the time it means we are physically attracted to them (which may change with time) or feel connected to them or care for them and have compassion for them. Which is all fine and dandy . . . but is that really love?
Ultimately, if you love someone you love everyone. I don't believe you can love just one person. If you think you can, then that's not real love. It may be a form of compassion, and there's nothing wrong with that - just that you've given it a false label.
When you see you true nature and become more present in your daily life, love will arise.
True love is to love all as one - simply because you will have seen who you are, and that won't be separate from the rapist, the drug dealer or the guy who has just beaten up a OAP for her loose change - we, you are not separate from them.
'You are the primordial energy of the universe coming on as whoever you are. I know I'm that, too. But we learn to define ourselves as separate from it.' Alan Watts.
Be aware and observe.
