वृद्धिह्रासभाक्त्वमन्तर्भावाद्, उभयसामञ्जस्यादेवम् ॥ २० ॥
vṛddhihrāsabhāktvamantarbhāvād, ubhayasāmañjasyādevam || 20 ||
vṛddhi-hrāsa-bhāktvam—Participating in the increase and decrease; antarbhāvāt—on account of its being inside; ubhaya-sāmañjasyāt—on account of the similarity in the two cases; evam—thus.
20. On account of Brahman being inside (Its adjuncts) (It appears) to participate in their increase and decrease. On account of this similarity in the two cases (mentioned in Sutra 18) it is thus (i.e. the comparison is not defective).
The comparison with the reflection of the sun is to be taken not on all fours but only with respect to a particular feature. Just as the reflected sun is distorted, trembles, or varies in size as the water shakes, expands, or contracts, while the real sun remains unchanged; so also Brahman participates, as it were, in the attributes of the Upadhis; it grows with them, decreases with them, suffers with them, and so on, but not in reality. Hence on account of this similarity in the two cases the comparison is not defective.
