Spiritual teachers exude love and peace because they’ve immersed themselves in love and peace.
Do you learn French by ignoring the French language and avoiding French people?
No, you learn French by immersion.
Love and peace are known through familiarity, they are not discovered by thinking.
If you want love and peace, seek them out directly in your heart.
Just as cats are the source of more cats and they're not the source of tomatoes, worry is the source of more worry - it's not the source of love. Don't wait to return to love until you've puzzled something out.
Let yourself dissolve into the love that you are in the very center of your heart, and everything will fall into place.
