Step 1: Understanding the Concept:
A 'Shakha' refers to a specific branch or school of a Veda. In ancient times, the Vedas were preserved through oral transmission within different family lineages or geographical centers, leading to slight variations in the arrangement of hymns and ritual practices. While the Charanavyuha mentions that the Rigveda once had 21 branches, only five main branches are traditionally recognized by the sage Shaunaka: Shakala, Bashkala, Ashvalayana, Shankhayana, and Mandukayana.
Step 2: Detailed Explanation:
Identifying the correct branch for each Veda is a fundamental skill in Vedic studies.
1. Bashkalashakha of the Rigveda: Among the five branches mentioned by Shaunaka, the Bashkala branch is highly significant. While the Shakala branch is the only one whose Samhita is fully extant and used today, the Bashkala branch is known through various citations in Brahmanas and Shrauta Sutras. It is said that the Bashkala Samhita contained 8 or 10 additional hymns (Khila-suktas) compared to the Shakala version. The study of Rigvedic branches is crucial for understanding the diversity of the early Vedic community.
2. Analysis of Incorrect Options:
- Kanvashakha: This is a prominent branch of the Shukla (White) Yajurveda. It is one of the two major surviving schools of the Madhyandina and Kanva traditions.
- Taittiriyashakha: This is the most popular branch of the Krishna (Black) Yajurveda. It has its own unique Samhita, Brahmana, Aranyaka, and Upanishad.
- Kauthumashakha: This is the most widely followed branch of the Samaveda today, especially in North India. Other Samavedic branches include the Jaiminiya and Ranayaniya.
3. Shaunaka's Classification: The Rigveda Pratishakhya and Charanavyuha are the primary authorities for these classifications. For the Rigveda, the student must remember the list: Shakala, Bashkala, Ashvalayana, Shankhayana, and Mandukayana. Any option outside this list belongs to a different Veda. In the current context of the Bashkalashakha, it is often associated with the Khila-suktas that appear at the end of certain Mandalas in the Rigveda.
Step 3: Final Answer:
Bashkalashakha is a branch of the Rigveda. Therefore, option (2) is correct.
