**2**^{nd}/21 Periods of the Cosmos, the **2**^{nd}/7 Periods of Restrained Quantum Gravity is the **Period of Divine Teleology Matched with Serendipity**, symbolized by the **2**^{nd}/7 *double* (כפולות) *letters*^{[1]} (ספרים) of Gimel (ג) matched with Gimel-dagesh (גּ) paired respectively (former rain and latter rain) with divine teleology (陽, defined instructional design and purpose); purposeful instructional design matched with serendipity or learning (陰, instructional design); Schrodinger teleology gives birth to or produces (生*Sheng*) the Period of the Impulse of Creation Matched with the Void.

Schrödinger equation is an equation that describes how the quantum state of a physical system changes in time. In classical mechanics, the equation of motion is Newton's second law used to solve for the motion of a mechanical system and mathematically predict what the system will do at any time beyond the initial settings and configuration of the system. In quantum mechanics, the analogue of Newton's law is Schrödinger's equation for a quantum system (usually atoms, molecules, and subatomic particles whether free, bound, or localized). It is not a simple algebraic equation, but (in general) a linear partial differential equation. The differential equation describes the wave function of the system, also called the quantum state or state vector.

**2**^{nd}/21 *Day-periods* of the Period of the Cosmos in Mayanism is transliterated as the **5**^{th}/20 *trecenas*, with the 1^{st}/13 *prime predominant* of *Ben*/*Acatl* beginning with the 54^{th}/260 count of days, with the ruling energy deity over the entire *trecena* of *Chalchihuitlicue* occurring during the **1**^{st}/4 worlds of the Mayan and the **2**^{nd}/5 suns of the Aztec.

**2**^{nd}/7 letters of the Hebrew term ABRAShITh (א**ב**ראשית); "will be in the beginning, first or origin," of Beth (ב) indexes the first chapter and first word of the Hebrew Torah as the *foundational concept restrained*, the same as the first seven of 20 periods *restrained* in the Mayan Underworld Terraces.

The *semi-dynamic image* (10-12 FPS) of the major arcana ^{[2]}(אר-כנע) tarot (טרות) trumps that corresponds to the 2^{nd} **Period of Divine Teleology Matched with Serendipity** is Most High Priestess symbolized by the Roman numeral II.
