deho ’savo ’kṣā manavo bhūta-mātrām
ātmānam anyaṁ ca viduḥ paraṁ yat
sarvaṁ pumān veda guṇāṁś ca taj-jño
na veda sarva-jñam anantam īḍe
dehaḥ—this body; asavaḥ—the life airs; akṣāḥ—the different senses; manavaḥ—the mind, understanding, intellect and ego; bhūta-mātrām—the five gross material elements and the sense objects (form, taste, sound and so on); ātmānam—themselves; anyam—any other; ca—and; viduḥ—know; param—beyond; yat—that which; sarvam—everything; pumān—the living being; veda—knows; guṇān—the qualities of the material nature; ca—and; tat-jñaḥ—knowing those things; na—not; veda—knows; sarva-jñam—unto the omniscient; anantam—the unlimited; īḍe—I offer my respectful obeisances.
Because they are only matter, the body, the life airs, the external and internal senses, the five gross elements and the subtle sense objects [form, taste, smell, sound and touch] cannot know their own nature, the nature of the other senses or the nature of their controllers. But the living being, because of his spiritual nature, can know his body, the life airs, the senses, the elements and the sense objects, and he can also know the three qualities that form their roots. Nevertheless, although the living being is completely aware of them, he is unable to see the Supreme Being, who is omniscient and unlimited. I therefore offer my respectful obeisances unto Him.
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.
