Answer: Light constantly surrounds us and affects us. We exist inside it. But the point is that Kabbalah speaks about the direction of the influence of light from the Creator to us and about how we can cause its influence on us.
A person who is in attainment consciously evokes the influence of light on himself. This is one impact. And there is another effect when the light affects him without his desire for it.
