What is the spiritual time and season?

If you have a variety of temperatures, how can flowers of different seasons in earth life bloom together in spirit life?

As to the flowers all blooming together, your earth world, with its variations of climate, warm in some places, cold in others, produces endlessly the essence or spirit of the finest and hardiest flowers to go on with their eternal growth. Thus, you see, when flowers once exist here, they will always exist, only subject to changes somewhat like the changes you have there. 

I know this will be enigmatical to you, but see its wisdom.

If one particular flower kept the same appearance, it would become monotonous, but it is not so. New buds and blossoms greet our sight [spiritual sight]―the old ones with their drooping heads, sending their spirit to the new.

―Spirit Samuel Bowles
