The "Connected Discourses with Lakkhaṇa" features venerable Mahāmoggallāna and venerable Lakkhaṇa. In these suttas, Moggallāna uses his clairvoyant vision to observe various spirits (petas) suffering due to their past unwholesome deeds. The Buddha confirms these visions, using them as teaching moments to illustrate the inescapable law of kamma and the severe consequences of unethical behavior. This collection serves as a stark reminder of the importance of moral conduct.
