Sanskrit:  तन्निर्धारणार्थनियमस्तद्दृष्टेर्पृथग्ध्यप्रतिबन्धःफलम्  
English:  There is no obligatory rule about that (ie., the meditations becoming connected always with rites), for that is obvious from the Upanishad, inasmuch as a meditation has a separate result, consisting in the elimination of hindrance to a rite.
