CC Madhya 21.1
śrī-caitanyaṁ likhāmy asya
agati-eka-gatim — to the only shelter for the conditioned souls who do not know the goal of life; natvā — offering obeisances; hīna-artha — of the necessities of the conditioned souls, who are poor in spiritual knowledge; adhika — increase; sādhakam — bringing about; śrī-caitanyam — unto Lord Śrī Caitanya Mahāprabhu; likhāmi — I am writing; asya — of Him; mādhurya-aiśvarya — of the sweetness and opulence; śīkaram — a small portion.
Offering my obeisances unto Śrī Caitanya Mahāprabhu, let me describe a particle of His opulence and sweetness. He is most valuable for a fallen conditioned soul bereft of spiritual knowledge, and He is the only shelter for those who do not know the real goal of life.
