Quoted below is from Shantideva's Bodhicaryavatara.
I cry aloud, looking for protection.
And I worship the Lord of the Thunderbolt. When they have seen him, the messengers of death and the other evil beings are frightened and they flee to the four directions.
I now go terrified to you for refuge—after having neglected your instruction, because of beholding fear. May you quickly extinguish fear.
What is the Buddhist explanation of this text?
Considering the list of excellence such as compassion, wisdom etc. mentioned prior to this text in the form of Bodhisattva, is it right to understand this as a personification of courage? or is it literally worship of the Lord of the Thunderbolt, be it Zeus or Indra, to extinguish fear?
