Sharing: The Whole Point
If the Light's nature is to share, then sharing is the fastest way to become like it. Kabbalah treats generosity as a spiritual technology, not just a virtue.
Everything in Rav Berg's Kabbalah leads back to one conclusion: the way to receive lasting fulfillment is to become a sharer. Sharing isn't only nice. It's the mechanism.
Like attracts like
Kabbalah describes the connection between you and the Light using the idea of "similarity of form." The more your nature resembles the Light's nature, the closer you are to it. The Light only shares. So each genuine act of sharing – of time, attention, money, patience or kindness – makes you more similar to the Light and, the teaching says, draws more of it into your life.
Sharing is harder than giving
Rav Berg's school makes a useful distinction. Giving can be reactive: we give to be liked, to feel superior, to get something back or to relieve guilt. Real sharing is proactive. It usually costs you a little, it often goes unnoticed, and it's done because it's right, not because it pays. That's why sharing with someone you don't like counts for so much more than sharing with a friend.
Tithing
One classic form of sharing is tithing – giving ten percent of your income. In Hebrew it's called ma'aser. Rav Berg's school teaches it as a spiritual practice: the tenth portion, they say, belongs to the Light and returning it protects the other ninety. You don't have to accept that framing to recognize an old wisdom in it: habitual giving loosens the grip that money has on us.
A practical note
Sharing is meant to be free. If any group ever pressures you to give more than you can afford, or ties your spiritual worth to a payment, that isn't sharing – it's a sales tactic. Give to causes you understand and trust, in amounts that are healthy for you.
