It is not just a question of consuming Time and Energy. It is a question of qualitative difference between the mental consciousness and the spiritual. The mental consciousness is a partial knowledge and hence it is termed as ignorance from the spiritual perspective. It scans the surface, sees one or at most few sides of a problem. Its vision is limited to the immediate narrow spectrum of Time and Space. Even when it tries to project into the future It cannot take into account the unexpected unknown forces that may come into play.
Spiritual intuition, on the other hand acts in a more comprehensive way. It has an access to those elements which the analytical mind dependent heavily upon the present organization of the material senses cannot. The principle behind is that there are higher and greater ranges of consciousness than the mind’s and spiritual life, where it is not restricted to inner peace, also activates these higher possibilities latent in everyone. Of course an inner calm and peace itself allows the mind to see better. But more than that, it opens the mind to a higher intuition and that is the real advantage.
