Verbal Testimony
The fourth pramana — verbal testimony from authentic and truthful authority (apta), including sacred texts and objective diagnostic observations.
Shabda: Authentic Testimony
Shabda means verbal testimony — that which is authentic and truthful. Sacred texts such as the Bible, the Koran, and the Vedas are considered authority, receiving this status from people called apta, those whose thoughts, feelings, and speech/actions are consistent.
In Ayurvedic practice, shabda extends beyond sacred texts to include objective diagnostic observations. X-rays, electrocardiograms, and MRIs are also considered shabda — objective testimony. If an ultrasound shows gallstones, we must believe it. Crucially, the patient is also one who knows the truth of their own experience. If the patient says they have a tummy ache, the practitioner must believe and listen with great respect.
