Sutra on the Original Vows of Ksitigarbha Bodhisattva

The Kṣitigarbha Bodhisattva Pūrvapraṇidhāna Sūtra (Sanskrit, Sutra of the Fundamental Vows of the Bodhisattva Kṣitigarbha) or Kṣitigarbhasūtra is a Mahāyāna sūtra teaching about the bodhisattva Kṣitigarbha and is one of the more popular sūtras in Chinese Buddhism. The sutra tells of how Kṣitigarbha became a bodhisattva by making great vows to rescue other sentient beings and a description of how he displayed filial piety in his past lifetimes. The sutra also expounds at length the retributions of unwholesome karma, descriptions of Buddhist hells and the benefits of good merit both great and small.
