On the 5th of Tammuz of the year 3332 from creation (429 BCE), Ezekiel, among the only prophets to prophesy outside of the Holy Land, beheld a vision of the Divine "Chariot" representing the spiritual infrastructure of creation.

About prophecy
During the summer months, from the Shabbat after Passover until the Shabbat before Rosh Hashahah, we study a weekly chapter of the Talmud's Ethics of the Fathers ("Avot") each Shabbat afternoon; this week we study Chapter Four.
Thoughts can give life. Thoughts can kill.
For example, a soldier. The Torah commands a soldier at war, “Do not allow your heart to weaken. Do not fear. Do not panic.”
Imagine this: An army is racing towards you. Your eyes have witnessed their savagery. How can you command your heart not to fear?
Maimonides explains: Don't think those thoughts and you will not fear. Dodge them as you dodge a flying arrow.
Because such thoughts threaten not only your life, they endanger the entire nation.
A soldier must think only one thought: What must I do right now?
Today, we are all soldiers.
