Baal HaSulam, “The Teaching of the Kabbalah and its Essence”: It is written, “For the commandment is a candle, and the teaching is light.” As one who has candles but no light to light them sits in the dark, one who has Mitzvot but no Torah sits in the dark. This is because the Torah is Light, by which the darkness in the body is illuminated and lit up.
There are people who perform many actions. They think that their deeds are correct, meaning they bring them closer to a great spiritual reward. Unfortunately, it is not true.
A person summarizes his life and thinks that he did a lot of good things, fulfilled many desires of the Creator (commandments), studied the Torah, learned by heart quite a number of sacred texts, and followed all the requirements. However, he suddenly begins to realize that he didn’t achieve anything since “a Mitzva (precept or commandment) without an aim is like a body without a soul.”
The physical actions he performed during his life did not bring any positive result. Life passed, and the person’s efforts and suffering occurred worthlessly. He will have to come back into this reality again, will be re-born, and will start all over from the cradle hoping that during this next reincarnation he will succeed much more.
This is how the same souls advance over and over again, from generation to generation, from life to life, until they arrive to their correct realization. After all, the purpose of life is not fulfilling physical actions, but rather in correcting our nature.
A commandment represents the correction of egoistic desire by the intention to bestow. This definition has to encourage us to evaluate whether we managed to correct at least one desire of ours and re-establish connection with other people.
