Question: Will the soul usually look the same throughout its incarnations?Sri Chinmoy: Yes, it will usually remain the same. But inside the soul is the psychic being, which will grow. Once it takes a form, the soul usually stays that way; but the psychic being grows gradually like a small child. At first it is very small, but then it grows up. In spiritual seekers the psychic being is better developed than in other human beings.
