नमो भगवते बुद्धाय
I'm reading Candrakīrti's madhyamakavatāra. I came across this passage -
"That they are the particular circumstance means that that which acts as the cause for the circumstance of being a tathāgata is the circumstance of being a bodhisattva. That they inspire the adoption refers to the case of noble Mañjuśrī who as a bodhisattva was the very first to inspire the illustrious Śākyamuni and the other tathāgatas to adopt the mind of awakening. Being thus regarded as the principal cause that enabled the final result, it is taught that the tathāgatas are born from the bodhisattvas."[1]
What is the story of the Noble Mañjuśrī inspiring Śākyamuni and other tathāgatas to adopt bodhicitta?
Thank you
