The soul, when it rises from earth to heaven
The Zohar presents the spiritual significance behind the Torah story and speaks of Abraham sitting under a hot, blazing sun when three people come to visit him. The blazing sun is a metaphor for the immense Light of the Creator revealed through the divine instrument of the Tetragrammaton and correspondingly, through the words of the Zohar.
The phrase blazing sun indicates that an extraordinary amount of spiritual Light is suddenly being revealed in this specific section of the Torah. This concept can be understood through the analogy of a light bulb. A bulb glows at a constant level of illumination. Just before the bulb burns out, however, there is a momentary burst of added light. The Zohar is our instrument to capture the intense spark of Light that is momentarily shining forth in this specific verse of the Torah.
