ātmānam anyaṁ ca viduḥ paraṁ yat
sarvaṁ pumān veda guṇāṁś ca taj-jño
na veda sarva-jñam anantam īḍe
Material scientists can make an analytical study of the physical elements, the body, the senses, the sense objects and even the air that controls the vital force, but still they cannot understand that above all these is the real spirit soul. In other words, the living entity, because of his being a spirit soul, can understand all the material objects, or, when self-realized, he can understand the Paramātmā, upon whom yogīs meditate. Nevertheless, the living being, even if advanced, cannot understand the Supreme Being, the Personality of Godhead, for He is ananta, unlimited, in all six opulences.
