Madame de Stael's quote suggests that living a spiritual life is not always easy. It implies that it is a challenging journey, instead of a peaceful and harmonious one. This is likely due to the reality that spiritual life needs an individual to stick to specific beliefs and practices, which can be challenging to preserve. It also recommends that religious life is not constantly a pleasant experience, as it can involve battles and challenges. This might be due to the fact that religious life frequently includes making sacrifices and dealing with hard decisions. Eventually, Madame de Stael's quote implies that religious life is not constantly simple, which it needs commitment and perseverance in order to achieve success.
"Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday"
