There are three well-known ingredients of the body. They have their origin in action, and are called Bile, Phlegm, and Wind. The body is called a union of these three. All living creatures are kept up by these three, and when these three become weakened, living creatures also become weakened. It is, therefore, that all persons well-versed in the scriptures of the science of Life call me by the name of Tridhatu.
त्रयो हि धातवः ख्याताः कर्मजा इति मे स्मृताः। पित्तं श्लेष्मा च वायुश्च एष संघात उच्यते॥ एतैश्च धार्यते जन्तुरेतैः क्षीणैश्च क्षीयते। आयुर्वेदविदस्तस्मात् त्रिधातुं मां प्रचक्षते॥
