妙法蓮華經玄贊 7.124

7.124

贊曰：下別喻。有四：一法王出世喻，二說教普滋喻，三稟潤各異喻，四不自覺知喻。「密雲彌布」是初喻也。「遍覆」以下是第二喻。化身隱實，八相漸現潛為廣利，如雲密而彌布，非卒暴雲，不為災故。雲有十德，頌中自釋。一化佛化三千大千同時出現，聲亦遍彼，故言遍滿大千世界。

The Commentary says: Below is the particular parable. It has four parts:
1. the parable of the Dharma King's appearance in the world;
2. the parable of the spoken teaching universally moistening;
3. the parable of receiving moisture differently;
4. the parable of not being consciously aware.
'Dense clouds spread across' is the first parable. 'Blanketing completely' onward is the second parable. The transformation body conceals the real, gradually displaying the eight phases to secretly bring about vast benefit, just as clouds are dense and spread across, not being sudden, violent clouds, so that they cause no disaster. Clouds have ten virtues, which are explained in the verses. A single transformation buddha transforms the three-thousand great-thousand [world], appearing simultaneously, and his voice also pervades it; therefore it says, 'filling the great-thousand world'.
