佛祖統紀 36.90

述曰。文帝嗣位之初。觀普賢無量壽二經。同時而至。至今持誦者為尤盛。是知元嘉之際尊敬大乘。五國來貢咸贊奉法。自渡江以來未有此時之光大也。

The Commentary states: At the beginning of Emperor Wen’s succession to the throne, the two sūtras of Contemplating Samantabhadra and Amitāyus arrived at the same time. Down to the present, those who uphold and recite them are especially numerous. From this one knows that during the Yuanjia era, the Mahāyāna was revered, and five states came to pay tribute, all praising and upholding the Dharma. Since the crossing of the Yangtze River, there had never been such glory as at this time.
