Concept: The Dasa Vatthūni (Ten Points) were ten controversial practices adopted by the Vajjian monks at Vaiśālī. These practices were considered violations or relaxations of the Vinaya rules and became the primary reason for the Second Buddhist Council, held nearly one hundred years after the Buddha’s Mahāparinirvāṇa.
Step 1: Understanding the historical significance of Dasa Vatthūni.
The Second Buddhist Council was convened to settle disputes regarding monastic discipline. The Vajjian monks had introduced ten practices that orthodox monks considered improper.
These ten points are recorded in the Vinaya Piṭaka, especially in the Cullavagga.
The question asks us to arrange the given five practices in their proper canonical order.
Step 2: Identifying the order of the given practices.
The traditional order of the relevant points is:
• Siṅgiloṇa-kappa
• Dvaṅgula-kappa
• Gāmantara-kappa (A)
• Āvāsa-kappa (E)
• Anumati-kappa (D)
• Āciṇṇa-kappa (C)
• Amathita-kappa (B)
Thus, among the options provided:
\[
A \rightarrow E \rightarrow D \rightarrow C \rightarrow B
\]
Step 3: Matching with the given options.
Now compare the obtained sequence with the choices:
• Option (1): Incorrect
• Option (2): Correct
• Option (3): Incorrect
• Option (4): Incorrect
Therefore, the correct sequence is:
\[
\boxed{A, E, D, C, B}
\]
Step 4: Final Conclusion.
The canonical order of the selected Dasa Vatthūni corresponds exactly with option (2). Hence, option (2) is the correct answer.
