• pāda — the feet (of the Lord)
  Pāda — the constant Gauḍīya object of meditation. Throughout this chapter (verses 8, 11, 15-16, 39, 40, 41-42, 43) the word recurs as the queens' single shared longing. Verse 2 plants it early: even sight of those feet destroys sin.
• īkṣā — by seeing
  From √īkṣ — to look. Gauḍīya śāstra ranks darśana of the Lord (or of His vigraha, His devotee, His Vraja-bhūmi) as itself purifying — no other sādhana required at the moment the gaze lands.
• hata — destroyed
  Past participle of √han. The sins are not gradually wiped but struck dead — same root as Kṛṣṇa's slaying of demons. Pāda-darśana is itself a weapon.
• aṁhasaḥ — whose sins
  Aṁhas — sin, narrowness, distress. The genitive frames the kings: those whose sins are slain. The verse stations the antidote (seeing Kṛṣṇa's feet) immediately beside the disease (aṁhas).
• hṛṣṭa — joyful
  From √hṛṣ — to bristle, to thrill. Hṛṣṭa-manas describes the precise Gauḍīya symptom of bhāva: the mind itself stands on end before the Lord. The reply that follows is not duty-speech; it is overflowing rasa.

• Where in my meetings with the Lord do I focus on content when the encounter itself does the work?
• What changes when I trust the meeting more than the words?

A traveller's dust is washed off the moment his feet touch the threshold of his own house — likewise the kings' inner stain falls away simply by their eyes resting on Kṛṣṇa's feet. Darśana of those feet is itself the bath; their joy in answering Him is the towel that dries them.
