“Where do all these chemicals come from? The answer is that they are produced by the inconceivable energy of the Supreme Personality of Godhead. Living entities are part of the Supreme Godhead, and from their bodies come many chemicals. For example, the lemon tree is a living entity that produces many lemons, and within each lemon is a great deal of citric acid. Therefore, if even an insignificant living entity who is but a part of the Supreme Lord can produce so much of a chemical, how much potency there must be in the body of the Supreme Personality of Godhead.” (Shrila Prabhupada, Chaitanya Charitamrita, Adi 16.81 Purport)
