If you take a closer look at the Tree of Life, you should notice that the tree branches out from Keter into three lines that connect Malchut (the last Sephira) to Keter . What does it mean, and why do we need these three lines?
The following paragraph from Baal-HaSulam explains it:
“And it is deemed a correction, called “the left rejects and the right adducts, meaning that that which the left rejects is considered correction. This means that there are things in the world, which from the beginning aim to divert a person from the right way, and they reject him from holiness.”
From this paragraph we can understand that there are two conflicting forces that operate within us – force of the left line that tries to push a person away from his path to spirituality, and the force of the right line that brings the person closer to the divine.
What does it mean and why would a Creator create us in a such non-perfect state?
Imagine yourself a situation: you’re hungry, very hungry actually. You think about the food all the time. In fact, all you can think about is food, and there is nothing else that enters your mind. You finally get a chance to eat, and satisfy your hunger – your desire for food. At this very moment, in which you’re full with food and can’t consume anymore – would you have any desire for more? Of course not!
The same happens in spirituality. Our advancement is made of ascends and descents. Descent is when we find ourselves in the left line – detached from the Creator, from spirituality, from the group. Unable to connect to the Upper Force, to comprehend what we read in Kabbalistic books, not capable to even physically to get to the class. We found ourselves rapidly decline from our level to attainment. This is the power of left line.
It’s important to understand why it happens. Similar to the example with food – if we don’t have “chisaron” – deficit of something – we would never want it (when we’re full, we don’t crave for food). So for us to desire higher spiritual state, we must first of all find ourselves in much lower state – in the state that would provoke us to desire more.
So all our advancement happens in three lines – in the left line that grows our desire, in the right line that helps us get closer to the spiritual, and in the middle line – where we actually advance and attain spirituality.
We can’t always exist in one line – we have to switch from one state to another – from up to down, from left to right – and the higher we descend, the higher stage we have the opportunity to attain.
