Answer: Because this is the only way you can rise above yourself and feel your gradual development. Only through gradual attainment are we able to grow new properties and facets within ourselves.
You can’t imagine how much work you are doing in the meantime. For example, you’ve been studying the wisdom of Kabbalah for two or three years. You say to yourself: “Why is it taking so long? All of this material could have been explained in a few months.” But the fact is, you are developing certain inner properties that you are completely unaware of now.
This is similar to the development of a small child. What does a child understand? In the first years of his life, he has no idea what’s happening. He simply exists! And how much he is developing all kinds of properties and how he perceives them—this is incomprehensible to him.
Similarly, when studying Kabbalah, we don’t understand what properties, new functions, and new internal blocks of perception and understanding are developing in us. Later, they all become revealed at once. As, for example, a boy in adolescence suddenly becomes a small man; the entire ripening period suddenly breaks through and reveals itself like a flower.
It’s the same with us, only much brighter. Childhood suddenly ends and real life begins in comprehension and sensations, and everything that has accumulated is revealed in a genuine, practical form.
