The branch of the Ramakrishna Math at Cossipore is popularly known as
Udyanbati. This garden house was sanctified by Sri Ramakrishna's stay with his disciples during the last few months of his life, as also by his
mahasamadhi. It was made a branch of Ramakrishna Math in 1946. Kalpataru Utsab
is organised on 1st Day of every year.
Significance of Kalpataru Utsav :
He knelt before the Master and said with folded hands, 'What can an insignificant person like myself say about the One whose glory even sages like Vyasa and Valmiki could not adequately measure?' The Master was profoundly moved. He said: 'What more shall I say? I bless you all. Be illumined!' He fell into a spiritual mood. Hearing these words the devotees, one and all, became overwhelmed with emotion. They rushed to him and fell at his feet. He touched them all, and each received an appropriate benediction. Each of them, at the touch of the Master, experienced ineffable bliss. Some laughed, some wept, some sat down to meditate, some began to pray. Some saw light, some had visions of their Chosen Ideals, and some felt within their bodies the rush of spiritual power
