• gāḥ su-alaṅkṛtāḥ — well-ornamented cows
  gāḥ (cows) + su (well) + alaṅkṛta (ornamented). Go-dāna is one of the most meritorious gifts in śāstra. Kṛṣṇa, the gopāla, gives cows to brāhmaṇas — a perfect circuit, the Cowherd dignifying both ends of the cow-economy.
• itihāsa-purāṇāni — epic histories and Purāṇas
  Compound: itihāsa (it happened thus — Mahābhārata, Rāmāyaṇa) + purāṇa (ancient narrative). Kṛṣṇa listens to the works that recount His own deeds. Gauḍīya signature: Bhagavān is the listener as well as the spoken-of; śravaṇa is enjoyed even by its subject.
• maṅgalāni — auspicious
  From maṅgala (auspiciousness). The narratives are maṅgala because they bear Kṛṣṇa's name. Gauḍīyas: śravaṇa-yogyam tad eva — that alone is fit to be heard which carries the Lord's pastimes.
• dvija-mukhyebhyaḥ — to excellent brāhmaṇas
  Compound: dvija (twice-born) + mukhya (chief, excellent), dative plural. The recipients of the gift are not any brāhmaṇas but the mukhyas — those whose qualifications are complete. Bhagavān-pratiṣṭhā goes to where dharma is most fully embodied.

• What sacred narrative am I hearing regularly enough to be shaped by it?
• Where could my charity be more deliberate and more dignified?

Two acts of one household: gifting decorated cows to brāhmaṇas, and listening in silence as the Purāṇas are recited at evening. The first is hand-charity, the second is ear-charity — and a fully formed gṛhastha keeps both open at once.
