There always have been and there always will be beautiful, evolved, and God-realized souls. Regardless of when they lived and where they lived, one can be in tune with their essence. Time and distance do not hinder the movement of grace.
Even if we do not have the physical presence of great sages in our life, we can have spiritual fellowship by creating a mental atmosphere filled with their vibrations and teachings.
My teacher used to tell me that there is always at least one perfectly God-realized soul somewhere in the Universe.
