Sojong 布薩 / 淨住、善宿、長養
Sojong (Wyl. gso sbyong; Skt. poṣadha; Pal. uposatha) 'Healing and Purification' — the bimonthly practice of confession observed by members of the monastic community. On sojong days the observance of the eight vows of sojong or the practice of Narak Kong Shak are recommended.
In Patrul Rinpoche's How to Keep the Eight One-Day Vows of a Layperson (bsnyen gnas yan lag brgyad pa'i sdom pa srung thabs) it says:
- The 'Second Buddha' of Oddiyana said:
In fact, the quote appears in Kalyanamitra's Extensive Commentary on Questions of the Vinaya ('dul ba dri ba rgya cher 'grel pa) as:
- All harmful deeds are perfectly purified in this.
- Since it restores (so) and purifies (jong) negativity completely
- The Tathagata has called this the practice of Sojong.
- This is clearly a reference to Guru Padmasambhava and others have attributed this quote to the dge tshul gyi lo dri ba, which is sometimes said to have been composed by Padmasambhava (although it has also been attributed to Sanghabhadra and even Atisha). However, this verse is not to be found in extant versions of that text preserved in the Tengyur. Others have suggested that the quote should properly be attributed to Vasubandhu, who is also known as the 'Second Buddha', but this is clearly not Patrul Rinpoche's intention as his reference to Oddiyana shows.
