naham prakasah sarvasya
mudho yam nabhijanati
loko mam ajam avyayam
Meaning: I am never manifest to the foolish and unintelligent. For them I am covered by My internal potency, and therefore they do not know that I am unborn and infallible.
*** O Supreme Personality of Godhead, O Supersoul, O master of all mystery, who can calculate your potency and pastimes in this world? You are always expanding Your internal potency, and therefore no one can understand You. Learned scientists and learned scholars can examine the atomic constitution of the material world or even the planets, but still they are unable to calculate Your energy and potency, although You are present before them.” The Supreme Personality of Godhead, Lord Krsna, is not only unborn but also avyaya, inexhaustible. His eternal form is bliss and knowledge, and His energies are all inexhaustible.
