Concept:
Mahayana Buddhism emerged as an important branch of Buddhism emphasizing:
• universal salvation,
• compassion,
• Bodhisattva ideal,
• and philosophical developments.
It differed significantly from Hinayana or Theravada traditions.
Step 1: Understanding the concept of Sunyata.
\[
\text{Sunyata}
\]
Sunyata means emptiness or voidness and became a central doctrine of Mahayana philosophy, especially in Nagarjuna’s Madhyamika school.
Thus:
\[
A \text{ is correct.}
\]
Step 2: Understanding the doctrine of Trikaya.
\[
\text{Trikaya}
\]
The Trikaya doctrine explains the three bodies of Buddha:
• Dharmakaya,
• Sambhogakaya,
• Nirmanakaya.
Thus:
\[
B \text{ is correct.}
\]
Step 3: Examining the concept of Arhat.
\[
\text{Arhat}
\]
The Arhat ideal is primarily associated with Hinayana or Theravada Buddhism rather than Mahayana.
Thus:
\[
C \text{ is incorrect.}
\]
Step 4: Understanding the Bodhisattva ideal.
\[
\text{Bodhisattva}
\]
The Bodhisattva ideal is the most important characteristic of Mahayana Buddhism.
A Bodhisattva postpones personal nirvana to help all beings attain liberation.
Thus:
\[
D \text{ is correct.}
\]
Step 5: Selecting the correct combination.
Correct statements are:
\[
A, B \text{ and } D
\]
Hence:
\[
\boxed{(2)\ A, B \text{ and } D \text{ Only}}
\]
Step 6: Importance of Mahayana Buddhism.
Mahayana Buddhism contributed greatly to:
• Buddhist philosophy,
• sculpture,
• monastic culture,
• and the spread of Buddhism to East and Central Asia.
