No matter what the situation, the sky is not affected by the clouds. It is free for all the living beings. The Buddha taught that the forces in the mind that bring suffering are able to temporarily hold down the positive forces such as love or wisdom, but they can never destroy them. The negative forces can never uproot the positive, whereas the positive forces can actually uproot the negative forces. Love can uproot the feelings of fear or anger or guilt because it is a greater power.

Love can go anywhere. Nothing can obstruct it from spreading its glory. I Am That, a book of dialogues with Nisargadatta Maharaj, includes an exchange between Nisargadatta and a man who complained a great deal about his mother. The man felt that she had not been a very good mother and was not a good person at heart. At one point of time, Nisargadatta advised him to love his mother. The man replied, “She wouldn’t let me.” Nisargadatta responded, “She couldn’t stop you.”

The Pali word metta has two root meanings. One is the word for “gentle.” Metta is likened to a gentle rain that falls upon the earth. This rain does not select and choose — “I’ll rain here, and I’ll avoid that place over there.”

Rather, it simply falls without discrimination. The foundation of metta practice is to know how to be our own friend. The other root meaning for metta is “friend.” To understand the power or the force of metta is to understand true friendship. — Beliefnet.com
