Knowledge of Natural Law
628. Why has the truth not been accessible to all in the past?
“Each thing must come in its own time. Truth is like light, you must adjust to it gradually otherwise it dazzles us.”
“To date, God has never allowed such comprehensive communications to be transmitted to the human race. Of course in ancient times there were individuals who were in possession of knowledge that they considered sacred and kept as a mystery from those whom they considered as profane. You must understand that, from what you know of the laws that govern these phenomena, only a few fragmentary truths were received, mixed together with generally illustrative and often vague lessons. Regardless, humankind should study every old philosophy, tradition or religion because they all contain the seeds of great truths. Although they may seem to contradict each other as they are misrepresented by worthless embellishments, today they are much easier to comprehend, thanks to the key that Spiritism has provided. Spiritism gives you a host of facts that up until now seemed to conflict with reason, but of which the reality is now unquestionably confirmed. You should continue to study every system because they bring a wealth of lessons and knowledge that may greatly contribute to your education.”
