Śrī Caitanya Caritamrta · Text Madhya 2.7
গম্ভীরা-ভিতরে রাত্রে নাহি নিদ্রা-লব ।
ভিত্তে মুখ-শির ঘষে, ক্ষত হয় সব ॥ ৭ ॥
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.
