When Śrī Caitanya Mahāprabhu inquired from Haridāsa Ṭhākura how he was to benefit living entities other than humans, Śrīla Haridāsa Ṭhākura replied that the Hare Kṛṣṇa mahā-mantra is so potent that if it is chanted loudly, everyone will benefit, including the lower species of life.
(Sri Caitanya Caritamrta---1:9:39---purport).

It is stated in the Caitanya-bhāgavata, Ādi-khaṇḍa, Chapter Two, that Haridāsa Ṭhākura was born in a village known as Buḍhana but after some time came to live on the bank of the Ganges at Phuliyā, near Śāntipura. From the description of his chastisement by a Muslim magistrate, which is found in the Sixteenth Chapter of the Ādi-khaṇḍa of Caitanya-bhāgavata, we can understand how humble and meek Haridāsa Ṭhākura was and how he achieved the causeless mercy of the Lord.
(Sri Caitanya Caritamrta---1:10:43---purport).

It is understood that Advaita Prabhu, at that time, was in His own paternal house at Śāntipura. Haridāsa Ṭhākura frequently used to meet Him. Coincidentally, therefore, he was also there, and upon the birth of Śrī Caitanya Mahāprabhu both of them immediately began to dance. But no one in Śāntipura could understand why those two saintly persons were dancing.
(Sri Caitanya Caritamrta---1:13:99---purport).

By the order of Lord Caitanya, both Nityānanda Prabhu and Haridāsa Ṭhākura used to preach the cult of Kṛṣṇa consciousness door to door. In the course of such preaching they found Jagāi and Mādhāi, two maddened drunken brothers, who, upon seeing them, began to chase them.
(Sri Caitanya Caritamrta---1:17:17---purport).

Later, when Haridāsa Ṭhākura went to Jagannātha Purī, he lived outside the temple, at a place called Siddhabakula. A monastery has now been erected there, known as Siddhabakula Maṭha. People who visit Jagannātha Purī often go to see Siddhabakula and the tomb of Haridāsa Ṭhākura, on the beach by the sea.
(Sri Caitanya Caritamrta---2:3:194---purport).

Haridāsa Ṭhākura and the Gosvāmīs were all engaged in chanting a fixed number of rounds; therefore chanting on beads is very important for everyone, even though one may become a paramahaṁsa.
(Sri Caitanya Caritamrta---2:4:125---purport).
