Metta
Metta means unconditional love, a wish for the happiness of a person without any expectations about that persons behavior or character.
In as much as I would like to be happy, so do all beings wish to be happy, may all beings be happy and contented.
Metta has a very special value for me as it has really helped me to connect to people around me. Many times in my life when there has developed ill feelings between myself and someone I have been able to make this much nicer by sending them good wishes of metta. I feel that sending people metta changes the way that you behave around them, and people notice this and then change the way they behave around you.
