If we only treat the patient by the Yoga (medicine) without considering the Dash pareekshy bhaava then

तस्माद्दोषौषधादीनि परीक्ष्य दश तत्त्वतः ॥३२६॥

कुर्याच्चिकित्सितं प्राज्ञो न योगैरेव केवलम् ।*

--If we only treat the patient by the Yoga (medicine) without considering the Dash pareekshy bhaava then definitely it's a hit and trial method and it's a short term success only.

*समीक्ष्य दोषौषधदेशकालसात्म्याग्निसत्त्वौकवयोबलानि (सि.अ.३)*

__This is the most important line to memorize and use in every case.
