Blended reading (Sanskrit + English inline)
gambhīrā-bhitare rātre nāhi nidrā-lava bhitte mukha-śira ghaṣe, kṣata haya saba
The small room beyond the corridor is called the Gambhīrā. Śrī Caitanya Mahāprabhu used to stay in that room, but He did not sleep for a moment. All night He used to grind His mouth and head on the wall, and His face sustained injuries all over.
