The body by its very nature impedes one’s capacity to grasp what transpires when he serves God, studies Torah, or fulfills mitzvot.
This innate impediment is the very thing allowing a person to study Torahand fulfill mitzvot. The inherent obstruction created by the body is the justification for the hybrid existence of body and soul.
Were a person aware of the powerful impact of his actions, he would explode.
That a person is able to sit and study Talmud, for example, lies in the fact that he is unaware of the force of his actions.
His ability to do so is only on account of the barrier that separates his sense of self from the connection to the Divine, to “the true One,” besides whom there is nothing else.
