Charak Samhita
कुर्याच्चिकित्सितं प्राज्ञो न योगैरेव केवलम् । निवृत्तोऽपि पुनर्व्याधिः स्वल्पेनायाति हेतुना ॥३२७॥
He must consider all the ten factors discussed earlier along with different types of factors, their classification and some exceptional rules while treating the disorders. As a small sparkle of fire flares up when it comes in contact with wind or wood and gets converted into huge flames of fire.
