According to Kabbalah (I studied at the Kabbalah Centre. Most Kabbalists disagree with the Kabbalah Centre’s take on Kabbalah… ) you EARN your light.
Light is everything that keeps you alive, everything that you enjoy, everything you value. Sustenance, sex, pleasure, fulfillment… everything.
Obviously you want more of it, and obviously you don’t want to work for it… unless you enjoy work…
Work here doesn’t apply only to work that you do to earn money. Anything that you have to do consciously against your own laziness, ego, dark side, is considered work in Kabbalah.
The Soul Corrections are a list of types of work, one can do to earn light. Tell the truth, face the tiger, reveal your dark side, let go of superiority, circulate money, honor, respect, care for and about others… lots of them, and you probably have heard at least most of them. You consider them virtues…
Now, like all useful systems, it works on checks and balances, and it can be rigged.
