I shall write here very clearly, as explained
In the Ornament of Manjushri's Buddha Land Sutra,
How, long ago, when Manjushri was Ambaraja,
He aroused the intention to become enlightened
Manjushri is the bodhisattva of wisdom. If you want to know more about him, you can read A Garland of Jewels by Ju Mipham, which is a collection of excerpts from the Mahayana sutras about the great bodhisattvas. The next several verses are verses of aspiration that Manjushri made about his enlightenment. Verses of aspiration are common in Tibetan Buddhism, and some compositions are well known.
Manjushri's aspirations are meant to serve as a model for us.
