• deva - yajanam — the place for worshiping the demigods
  Compound: deva + yajana. The technical name for the consecrated sacrificial ground. Gauḍīyas note that the soil itself must be made fit before yajña — outer order mirrors the inner.
• svarṇa — gold
  Su (good) + varṇa (colour). Vedic culture uses gold not for show but as the metal that does not corrupt — fit for what must remain undefiled. Even ploughing is done with the incorruptible.
• yathā - āmnāyam — according to the standard authorities
  Compound: yathā (as) + āmnāya (received tradition, śruti). The Rājasūya is performed exactly by the book — this matters, because the verse-cluster ahead will not break the book; it will reveal what the book was always pointing to (Kṛṣṇa).
• dīkṣayām cakrire — they initiated
  Periphrastic perfect of √dīkṣ. Dīkṣā here is the yajamāna-dīkṣā — the king's consecration as sacrificer. Gauḍīyas link the broader sense: dīkṣā transmits adhikāra; only after it may the rite proceed.

• What 'ground' in my life needs plowing before I can offer well?
• Where am I trying to harvest where I have not yet broken the soil?

Before a temple is built, the priests turn the soil with a golden plough so that every furrow remembers its purpose. The Rājasūya's earth is opened with svarṇa-lāṅgalas — even the ground beneath the yajña is dignified before the first oblation is poured.
