Charkra... -You can learn about the body, in that we have a head, arms, legs ect and do fine with just that knowledge. But if you want to find out how each part works in conjunction with each other and how they affect you then you have to go deeper learn about how the muscle,nervous system..well the anatomy you could even go deeper with dna. Your right though in saying you dont need to learn it yet, but it does help to understand how it can relate to your spiritual growth.
