Kṣitigarbha Bodhisattva Pūrvapraṇidhāna Sūtra
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. History

The Kṣitigarbhasūtra was first translated from Sanskrit into Chinese in the 7th century during the Tang dynasty by the Tripiṭaka master Śikṣānanda, a monk from Khotan who also provided a new translation of the Avataṃsaka Sūtra and the Laṅkāvatāra Sūtra. Some scholars suspected that instead of being translated, this text may have originated in China since no Sanskrit manuscripts of this text have been found. Part of the reason for suspicion is that the text advocates filial piety, which is commonly associated with Confucianism in Chinese culture. Since then, other scholars such as Gregory Schopen have countered that Indian Buddhism also had traditions of filial piety. One example is the Buddha's sharing of the dharma in the form of Abhidhamma with his late mother who was reborn as a celestial being in the abode of Tavatimsa, which was the greatest gift that he could offer out of filial piety to his late mother. Currently, there is no clear evidence indicating either an Indian or Chinese origin for the text. Contents
There are a total of thirteen chapters in the Kṣitigarbhasūtra, which are divided into three sections. The teaching is presented in the form of a dialogue between the Buddha and Kṣitigarbha and takes place in the Trāyastriṃśa Heaven, located on the top of Mount Meru, in front of a vast multitude of sentient beings. It includes tales of Kṣitigarbha's skill at freeing beings from the hells and instructions on dealing with the dying and the dead. This sutra has multiple aspects for buddhists who are in various condition. For example,

 A dharma to 'leave the sea of suffering and realize the happiness of Nirvana' and finally 'Ultimate attainment of Buddhahood'. A teaching concerning karmic retribution, graphically describing the consequences one creates for oneself by committing undesirable actions. filial piety – not only that between oneself and one's parents, but also in an ultimate sense of a universal code of duty or responsibility for all living beings. For example, the Buddha frequently mentions the benefits of dedicating any good merit done to all sentient beings: "Moreover, if they should be able to dedicate rewards thus gained for the benefit of the entire Dharmadhatu, then their bliss will defy comparison." In the last Chapter 13, Buddha also spoke about 28 kinds of benefits for "any good man or good woman who should see Ksitigarbha's image and hear this Sutra and, furthermore, read and recite it, and who should also  donate incense, flowers, drink, food, clothing and precious treasures as  offerings, in addition to giving praise and making obeisance to Bodhisattva Ksitigarbha"
