Attributed to Ramakrishna, there is the quote, "Nem o Sol nem a lua podem refletir-se claramente na áuga lamacenta. Assim a alma universal não pode realizar-se perfeitamente em nós, equanto não afastarmos o véu da ilusão, isto é, equanto perdura o sentimento do eu e do meu."
Which translates to English as follows: "Neither the sun nor the moon can be clearly reflected in the muddy water. Thus the universal soul can not be perfectly realized in us, as long as we do not remove the veil of illusion, that is, as long as the sentiment of self and mine persists."
Ramakrishna was an Indian mystic and yogi during the 19th century.
