Intelligence, goodness, humanity, excitement, serenity. Over time, these are the things that change the musculature of your face, as do laughter, and animation, and especially whatever peace you can broker with the person inside. It's furrow, pinch, and judgement that make us look older - our mothers were right. They said that if you made certain faces, they would stick, and they do. But our mothers forgot that faces of kindness and integrity stick as well.
Just as a mother would protect with her life her own son, her only son, so one should cultivate an unbounded mind towards all beings, and loving-kindness towards all the world. One should cultivate an unbounded mind, above and below and across, without obstruction, without enmity, without rivalry. Standing, or going, or seated, or lying down, as long as one is free from drowsiness, one should practice this mindfulness. This, they say, is the holy state here.
Little children play with dolls in the outer room just as they like, without any care of fear or restraint; but as soon as their mother comes in, they throw aside their dolls and run to her crying, "Mamma, mamma." You too, are now playing in this material world, infatuated with the dolls of wealth, honour, fame, etc., If however, you once see your Divine Mother, you will not afterwards find pleasure in all these. Throwing them all aside, you will run to her.
As clichéd as it sounds, relationships between women do shape so much of our understandings of ourselves, starting with our mothers. I think all women can relate to the feeling of having merged with best friends. We begin to look alike, talk alike, even take on the same mannerisms. They are as close as family. We give a lot of attention to the heterosexual, nuclear family, but our friends determine as much, I bet, of who we are, how we feel, and how we behave.
