Step 1: Interpretation of the statement.
The text emphasizes agriculture's paramount significance, identifying it as the foundation of wealth, intellect, and existence.
Step 2: Source identification.
This passage is attributed to Parāśara, a venerated ancient sage recognized for his contributions to agricultural literature and considered the progenitor of agricultural science in Vedic traditions.
Step 3: Exclusion of alternatives.
- Bharadvāja: Primarily associated with Ayurvedic medicine and martial disciplines, not this particular quotation.
- Kanāda: The originator of the Vaiśeṣika philosophical system, with no known connection to agriculture.
- Kapila: The founder of Sāṅkhya philosophy, unrelated to the content of this verse.
Step 4: Final determination.
Consequently, the verse originates from Parāśara.
