Śaṅkarācārya's commentary

The essence of water is sapidity. In Me who am that sapidity waters are woven. — So in all cases. — Just as I am the sapidity in waters, so am I the light in the moon and the sun; I am the Praṇava, the syllable Oṃ in all the Vedas: in Me who am that Praṇava all the Vedas are woven. So also, I am humanity in men, i.e., I am that in a person which makes that person regarded a human being. In Me as humanity all persons are woven. Sound is the essence of ākāśa: in Me as sound ākāśa is woven.
