Hora Sara
मातापितृदोषाभ्यां क्वचिन्निरुद्धं दशाफलं ज्ञेयम्। तस्माद्योगान् सम्यक् परीक्ष्य पश्चाद्दशाफलं चिन्त्यम्॥२१॥
On account of the sins committed by the two parents—the mother and the father—there may be a break in the happening of the effects in certain cases. It is therefore imperative that the Yogas should be first examined carefully before any attempt is made to predict the effects of a Dasa.
