sa ekadaradhana-kala atmavan
grhita-mauna-vrata isvaram harim
jata-dharas tapasa apluto ’cyutam
samarcayam asa kulacalasramah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Indradyumna Maharaja retired from family life and went to the Malaya Hills, where he had a small cottage for his asrama. He wore matted locks on his head and always engaged in austerities. Once, while observing a vow of silence, he was fully engaged in the worship of the Lord and absorbed in the ecstasy of love of Godhead.
