Important of practical training
In spite of the student having studied and understood the meanings (implications) of the science fully (after completing the study) he should be made a Yogya (fit person – expert in practical training). He should be instructed in the practical methods of medical therapies including oleation, sudation etc. and surgical therapies like excising etc. In spite of being well read (and equipped with good theoretical knowledge), he becomes unfit (incompliant for surgical activities) if he is not made yogya – well equipped and well trained in practical training.

A Verse here: –
In this manner, the intelligent (student) who has been made fit i.e., practically trained by the use of things which are suitable for practical training, as described in the science, does not falter in his actions.
Hence, he who desires skill (expertise) in the use of sharp instruments, alkaline and thermal cautery etc. should make use of objects similar (suitable) to the act and become fit (skilled in surgical work).
Notes: – What we have to appreciate from the foregoing description is the utmost importance our ancient teachers had given to practical training in surgical activities, their ingenuity in selection of commonly used things and artificially prepared models suitable for each technique and their effort to make every student fit to perform all surgical activities.
Thus ends the Ninth chapter by name Yogyasutriya, in Sutra Sthana of Susruta Samhita.
