• muhūrtam — for a moment
  A muhūrta — roughly forty-eight minutes, but used here for a brief while. Vraja's blindness is timed; Kṛṣṇa's līlās of separation are always bounded. Gauḍīya commentaries emphasize: the Lord never withdraws from His pure devotee for more than a muhūrta — the apparent separation is fuel for deeper union.
• rajasā — by big particles of dust
  Rajas — dust, but also the guṇa of passion. The double-meaning is exact: when rajas covers the senses, the soul cannot find the Lord just placed in front of it. Tṛṇāvarta is rajo-guṇa materialized as wind.
• tamasā āvṛtam — covered with darkness
  Tamas — darkness, the guṇa of ignorance. Rajas + tamas together pile up across the verse. The Gītā's diagnosis (14.5–8) is precisely this — rajas agitates and tamas covers; their combined work is the inability to perceive the ever-present Lord.
• nyastavatī — she had placed
  From ni-as, to set down. The crucial verb: she placed Him there. The Gauḍīya principle of nyāsa — placing — runs through all bhakti. When the storm clears, the Lord will be exactly where the devotee has nyāsa-ed Him; He does not leave. The fault, when seeing fails, is never with His position.

• Notice the moments today when sudden agitation — rajas and tamas as a literal dust storm — obscures your remembrance of Kṛṣṇa, and pause until the air clears rather than acting from that blindness.
• Refuse to conclude that Kṛṣṇa is absent simply because your senses cannot find Him; return to the place where you last 'set Him down' — your japa, your prasāda offering, your morning sādhana — and resume there.
• Speak to Kṛṣṇa with the protective bhāva of Yaśodā today: stand guard over your remembrance of Him as a mother stands guard over her child in a storm.

A diya placed on the windowsill of one's own house is sometimes invisible behind a sudden gust of curtain — but it has not gone anywhere; the curtain has merely settled between the eye and the flame. Yaśodā cannot see Kṛṣṇa, but He is precisely where she placed Him, only the dust hangs in between.
