chiṇḍā kāni kāṅthā vinā nā pare vasana
sāvadhāne prabhura kailā ājñāra pālana
Synonyms: 
chiṇḍā kāni — a small torn cloth; kāṅthā — a patchwork cotton wrapper; vinā — except; pare — does not wear; vasana — clothing; sāvadhāne — with great care; prabhura — of Śrī Caitanya Mahāprabhu; kailā — performed; ājñāra pālana — execution of the order.
Translation: 
He never touched anything to wear except a small torn cloth and a patchwork wrapper. Thus he very rigidly executed the order of Śrī Caitanya Mahāprabhu.
Purport: 

The principle of very rigidly carrying out the order of the spiritual master must be observed. The spiritual master gives different orders to different people. For example, Śrī Caitanya Mahāprabhu ordered Jīva Gosvāmī, Rūpa Gosvāmī and Sanātana Gosvāmī to preach, and He ordered Raghunātha dāsa Gosvāmī to strictly follow the rules and regulations of the renounced order. All six Gosvāmīs strictly followed the instructions of Śrī Caitanya Mahāprabhu. This is the principle for progress in devotional service. After receiving an order from the spiritual master, one must strictly try to execute the order. That is the way of success.
