Question: Can aspiration significantly change the soul's capacity?

Sri Chinmoy: The soul has all capacities. It is only the physical mind, the vital and the body-consciousness that need the capacity to do the right thing and grow into the right thing. If you sincerely aspire, then your aspiration will significantly increase your capacity in every part of your existence.
