Some suggest elements depict a sundial, with the「sun carefully measured on ground」perhaps marks the MOMENT, the TIME or the HOUR. The Sun's path and shadows cast on the ground change with the SEASONS and were「carefully measured」although a sundial often fails to perform well on a cloudy day, and at night, when standing in a forest, or near any other mountains, and so on…no to mention that the time could accurately be told only while standing within a narrow scope of land, and, that such a timepiece is not portable, generally, other than the wrist-type models. However, those explanations do not account for the additional meanings of CHANCE, OPPORTUNITY, FLOURISH, PROSPER, or TO BEAT FAST…(?): note that the original elements for「temple」were likely not「ground, with careful hand measurements」but「a male, penis in a squeezing grip」as the temple of the local shaman: today, some temples in Japan recognize this, displaying the glyph with the「man, penis」element. Those memorable MOMENTS, TIME, OCCASIONS in the「tonguing mouth temple」with「man, penis」in a「squeezing grip, rod streaming with emphasis, throbbing, pulsating」might more accurately portray the moments and times that a male patron remembers most. Tonguing temple of the local shaman may also represent her manner of charging for services by TIME, or the HOUR, or by each OCCURRENCE of some unequivocal event, such as coming, or going into a「tonguing temple.」
Perhaps EPOCH, AGE, SEASON refers to the span of time early in a relationship when「tonguing mouth with penis in squeezing grip」still occurs but later comes to an end, not something that seems to last a long while or to continue indefinitely unless some duress is applied (or, some fee is paid).
Mnemonic with Japanese elements: imagine time was measured by temple priests needed for prayers and rituals, perhaps using religious edifices and temple sundials (hours), a building's shadow (seasons, annual cycles, using pyramids in other parts of the world), or huge rocks such as Stonehenge (long-term EPOCH, AGE). Even today, temple gongs in a squeezing grip mark times of each day, the end of the year, and other occasions.
