注大乘入楞伽經 6.173

6.173

明此形轉變，譬如以金作諸器服，則有種種形狀不同，言有轉變，非金性變也。一切諸法轉變亦爾。妙明真體常住不易，凡夫外道無有知者。

This clarifies transformation of shape: for example, using gold to make various utensils and ornaments results in different shapes; though one says there is transformation, the nature of gold does not change. The transformation of all dharmas is also like this. The wondrous and luminous true essence is eternally abiding and unchanging, but none of the ordinary beings and non-Buddhists understand this.
