People don’t know what the state of Lishma is, and often use this name to label completely non-spiritual states. They don’t understand that to attain Lishma is a great work, which is impossible without studying Kabbalah, the group, and obeying the rules of ascension explained by the Kabbalists.
In fact, Lishma means that you rise above your egoism and are entirely in bestowal. In the quality of bestowal, you see the spiritual world, and in this world, you exist only for the sake of spirituality. You identify yourself entirely with your soul, but your body still needs to be healthy in order to exist in both worlds. The soul can’t really advance if its other half, the body, doesn’t exist in this world. The soul needs the body until the very last step.
People don’t understand that to attain the quality of bestowal, Lishma, one has to draw the Light that returns us to the source of bestowal, to equivalence to the Creator. Afterward, a person is called “angel”, meaning he is openly receiving the Creator’s orders and following them through. He either “hears” or “sees” the Creator. He uncovers the Upper System, his relationship with the Creator in the Light Hassadim or maybe even Hochma. This attainment doesn’t have anything to do with the quantity and quality of knowledge, but only the measure of attainment of the quality of bestowal and love.
