Charak Samhita
रसस्य च न रागोऽस्ति स कथं याति रक्तताम्। द्रवाद्रक्तात्स्थिरं मांसं कथं तज्जायते नृणाम्॥२३॥
Rasa is in fact colorless, and how does it attain the red color of rakta? How is it that a solid structure such as mamsa is formed out of rakta which is a fluid by its nature?
english translation
rasasya ca na rAgo'sti sa kathaM yAti raktatAm। dravAdraktAtsthiraM mAMsaM kathaM tajjAyate nRNAm॥23॥
