Importance of Yukthi
Without intelligence or assessment, knowledge cannot be totally acquired.
Yukti is necessary to assess taste (rasa), quality (guna), potency (veerya), post-digestion taste (vipaka), functions (karma) of any substance.
Yukti is necessary to understand the action of sharp and blunt instruments (Shastras and Yantras) and medicines (Aushadha) on the body.
Collection of medicines, purification, formulation and storage is done based on Yukti.
Assessment of the stage of disease progression (Kriya kala), identifying a disease, its treatment, medicine and its dose, time of medicine administration etc are decided based on Yukti.
