Let there be light!-Let there be light!
יְהִי אוֹר-יְהִי אוֹר
The first light travels one way while the second light travels in the reverse direction. The second light will be revealed to us in the World of the Earth (our universe which was separated at the time of the "Spritual Big Bang"-the division of the Name "Hai") at the End, which is in fact the Beginning.
This explains with relative simplicity how energy/subatomic particles and time moves both backwards and forwards simultaneously and explains why light can be viewed in our world as both a wave and a particle.
Light which is THE source of energy can be viewed both physically as a particle and metaphysically as a wave (or vice versa) by Man whom Hashem created "in His Image", and as such are partners with G-d in Creation. Thus mans act of observance (participation) of the Light is crucial to the outcome of the light's behavior- whether the light will be considered as a wave or a particle.
What we call an observed "miracle" on earth is simply a manifestation/revelation of the Metaphysical World in our physical world (8 in 1) which is brought about by the prayers of a Tzaddik (Righteous Person) in order to perform Hashem's will on earth.
This is why our Sages teach us:
A Tzaddik Decrees and Hashem Performs (the decree)
צדיק גוזר והקדוש ברוך הוא מקיים
1381+6 words=17=8 or 2321=8
How can a Tzaddik do this?
Because he stands at the mid-point of the double Sphirotic system of two halves and aligns himself with the Will of Hashem.
Ultimately there will be unification of the "two" lights which is in the mid-point of infinity where there is no past present or future, no division, just the pure Divine Light of The Ain Sof.
