If was once at an intimate concert in which the performer, a deeply spiritual person, gazed warmly at his audience and said, "I want you to know, I love you all." I smiled tolerantly and thought, "Sure." Looking back, though, I realize my cynicism was misplaced. This man naturally saw the good in others, and our being there said enough about us that he could love us. Judaism actually idealizes this universal, unconditional love.

Obviously, there's a huge distance from here to the far more profound, personal love developed over the years, especially in marriage. But seeing goodness is the beginning.

  Actions Affect Feelings: 

     Now that you're feeling so warmly toward the entire human race, how can you deepen your love for someone? The way God created us, actions affect our feelings most. For example, if you want to become more compassionate, thinking compassionate thoughts may be a start, but giving tzedaka (charity) will get you there. Likewise, the best way to feel loving is to be loving ― and that means giving.
While most people believe love leads to giving, the truth (as Rabbi Eliyahu Dessler writes in his famous discourse on loving kindness) is exactly the opposite: Giving leads to love.
What is giving? When an enthusiastic handyman happily announces to his non- mechanically inclined wife, "Honey, wait till you see what I got you for your birthday ― a triple-decker toolbox!" that's not giving. Neither is a father's forcing violin lessons on his son because he himself always dreamed of being a virtuoso.
True giving, as Erich Fromm points out, is other-oriented, and requires four elements. The first is care, demonstrating active concern for the recipient's life and growth. The second is responsibility, responding to his or her expressed and unexpressed needs (particularly, in an adult relationship, emotional needs). The third is respect, "the ability to see a person as he [or she] is, to be aware of his [or her] unique individuality," and, consequently, wanting that person to "grow and unfold as he [or she] is."
These three components all depend upon the fourth, knowledge. You can care for, respond to, and respect another only as deeply as you know him or her.

Opening Yourself to Others:                                                                                                                               The effect of genuine, other-oriented giving is profound. It allows you into another person's world and opens you up to perceiving his or her goodness. At the same time, it means investing part of yourself in the other, enabling you to love this person as you love yourself.
