The correct option is Sutta Pitaka.
Explanation
The Buddhist scriptures are collectively known as the Tripitaka (Three Baskets). These are the Vinaya Pitaka (rules of discipline), the Sutta Pitaka (discourses/sermons), and the Abhidhamma Pitaka (philosophical analysis). The specific discourse mentioned in the question is the Sigalovada Sutta.
Detailed Analysis
- Sutta Pitaka (Correct): The Sigalovada Sutta is the 31st discourse found in the Digha Nikaya (Collection of Long Discourses), which is the first of the five divisions of the Sutta Pitaka. In this sutta, the Buddha advises a householder named Sigala on domestic and social ethics, including the reciprocal duties between parents and children, teachers and students, husbands and wives, friends, employers and servants, and laypeople and religious guides. It is often referred to as the "Vinaya of the Householder" (Code of Discipline for Laymen).
- Vinaya Pitaka (Incorrect): This basket deals primarily with the monastic rules and regulations for the Sangha (monks and nuns). It focuses on the conduct of the ordained rather than the lay householders.
- Abhidhamma Pitaka (Incorrect): This basket contains the higher teachings, focusing on the metaphysical, psychological, and philosophical analysis of the Buddha's doctrine.
- Dipavamsa (Incorrect): This is the oldest historical chronicle of Sri Lanka, written in Pali. It is not one of the three main Pitakas containing the Buddha's direct sermons.
Key Takeaway
The Sigalovada Sutta, which outlines the code of conduct and ethical duties for laypeople (householders), is contained within the Digha Nikaya of the Sutta Pitaka.
