Concept:
Buddhist ethical life is built upon morality, discipline, charity, communal harmony, and observance practices. Both monks and householders participate in these practices according to their spiritual responsibilities. Terms like Śīla, Uposatha, Dāna, and service to the Saṃgha form the practical foundation of Buddhist social and spiritual life.
Step 1: Understanding Observation of Śīla.
Śīla refers to moral discipline and ethical conduct.
It includes restraint of body, speech, and behavior through observance of precepts such as:
• Non-violence
• Truthfulness
• Non-stealing
• Purity of conduct
• Avoidance of intoxicants
The practice of Śīla controls unethical tendencies and establishes moral purification.
Therefore:
\[
Observation of Śīla \rightarrow Moral Control
\]
Hence:
\[
A \rightarrow II
\]
Step 2: Understanding Uposatha.
Uposatha is a sacred observance day in Buddhism.
It is traditionally observed during:
• Full moon
• New moon
• Quarter moon days
On these days practitioners often:
• Fast
• Meditate
• Listen to Dharma
• Observe additional vows
Hence, Uposatha corresponds to:
\[
Special fasting day
\]
Thus:
\[
B \rightarrow IV
\]
Step 3: Understanding Service to Saṃgha.
The Saṃgha is the monastic community of monks and nuns.
Lay followers support the Saṃgha through:
• Food offerings
• Monastery maintenance
• Organizational help
• Participation in religious activities
Thus, service to Saṃgha essentially means:
\[
Cooperation with Bhikṣusaṃgha
\]
Hence:
\[
C \rightarrow III
\]
Step 4: Understanding Charity (Dāna).
Dāna means generosity or charitable giving.
For Buddhist householders (Gṛhasthas), Dāna is one of the primary virtues. Through charity, the householder supports monks, temples, and needy beings while cultivating detachment and compassion.
Thus:
\[
Dāna \rightarrow Service as householder
\]
Hence:
\[
D \rightarrow I
\]
Step 5: Final Conclusion.
The final matching becomes:
\[
A-II,\quad B-IV,\quad C-III,\quad D-I
\]
Therefore, the correct answer is:
\[
\boxed{(4)}
\]
