Another Sanskrit Buddhist scripture from the Prajnaparamita texts, and that became known in China, is the Diamond Sutra. The earliest copy known from this sutra is from 868 CE, and was found along the Silk Road.
This sutra concerns teachings of the Buddha himself. In this sutra the Buddha tells Subhuti, one of his disciples, that all forms in the world are ultimately illusory (empty).
This illusoriness includes even the Buddhist Dharma as we perceive it. Therefore in order to gain enlightenment we have to give up attachment to the Dharma as well.
So human destiny in this context means giving up all attachments in order to seek enlightenment that is beyond the scope of our everyday understanding.
