Question: Does the voice change through the different ages?
Answer: Yes. Every age, infancy, childhood, youth, and more advanced age changes the pitch of the voice. The advanced age is an expression of what a person has gained, and so the voice is also indicative of his attainment. No doubt, as with every step in the age of a person, so with every step forward in spiritual evolution, there is also a difference in the voice. Every experience in life is an initiation. Even in the worldly life it is a step forward, and that experience changes the voice.
