In traditional Hindu classification, which of the following is NOT counted as an Upaveda (sub-Veda)?

Introduction / Context:
In traditional Hindu learning, the four main Vedas are Rigveda, Yajurveda, Samaveda and Atharvaveda. Alongside them, there is a concept of Upavedas (sub Vedas) which are specialised texts on practical sciences such as medicine, music, warfare and architecture. Understanding which texts are primary Vedas and which are Upavedas is useful for questions on ancient Indian literature and knowledge systems.

Given Data / Assumptions:

• The question asks which option is not counted as an Upaveda (sub Veda).
• Options include Ayurveda, Yajurveda, Gandharva Veda, Shilpa Veda and Dhanurveda.
• We know there are four main Vedas and several associated Upavedas.

Concept / Approach:
The main Vedas are: Rigveda, Yajurveda, Samaveda and Atharvaveda. The Upavedas are traditionally listed as texts like Ayurveda (medicine), Dhanurveda (warfare/archery), Gandharvaveda (music and performing arts) and Shilpa or Sthapatyaveda (arts, crafts and architecture). Since Yajurveda is one of the four primary Vedas, it cannot be classified as an Upaveda. The others in the option set correspond to recognised Upaveda categories.

Step-by-Step Solution:

Verification / Alternative check:
Classical lists in traditional scholarship and in modern reference works describe four Vedas and four Upavedas. Commonly, Ayurveda, Dhanurveda, Gandharvaveda and Shilpaveda or Sthapatyaveda are mentioned as Upavedas. Yajurveda appears only in the list of primary Vedas and not under Upavedas. This confirms that the classification used in textbooks matches the reasoning above.

Why Other Options Are Wrong:

• Ayurveda: Recognised as an Upaveda dealing with the science of life, health and medicine.
• Gandharva Veda: Considered an Upaveda related to music, dance and performing arts.
• Shilpa Veda (Sthapatya Veda): Treated as an Upaveda concerned with architecture, sculpture and crafts.
• Dhanurveda: Traditionally an Upaveda focused on warfare, archery and military science.

Common Pitfalls:
Many learners confuse the names of the four main Vedas with the names of Upavedas because some Upavedas also end with 'veda'. A quick way to avoid confusion is to memorize the four primary Vedas first and treat anything outside that list—like Ayurveda or Dhanurveda—as potential Upavedas. When you see Yajurveda in a list that mostly contains clearly auxiliary texts, it should stand out as the main Veda and therefore not a sub Veda.

Final Answer:
Correct answer: Yajurveda.
