"I cannot but think that it would be a great step if mankind could familiarise themselves with the idea that they are spirits incorporated for a time in the flesh re spirits incorporated for a time in the flesh"

In this quote, Catherine Crowe is revealing her belief that it would be beneficial for humanity to understand and accept the concept that we are spiritual beings temporarily occupying physical bodies. She suggests that if we might become more comfortable with this concept, it might cause a considerable development for mankind. This could potentially result in a deeper understanding of our function and existence, and possibly even a higher sense of connection to the spiritual realm. By acknowledging our spiritual nature, we may have the ability to tap into a greater level of consciousness and live more satisfying lives.
