SUNDAR, BHĀĪ, a Chaḍḍhā Khatrī resident of Āgrā, was a devoted Sikh of the time of Gurū Hargobind (1595-1644). He served the saṅgat diligently and made regular visits to Amritsar to see the Gurū. Once as he entered the Guru's presence, he asked how a gurū helped the disciples in attaining liberation. Gurū Hargobind, says Bhāī Manī Siṅgh Sikhāṅ dī Bhagat Mālā, told him how Gurū Nānak had enjoined upon the Sikhs to attend the saṅgat where in they, through reciting and listening to the holy śabad with faith, would attain spiritual enlightenment and ultimately become one with the Formless Being. "It is the sādh saṅgat, holy congregation," explained Gurū Hargobind, "which liberates; no other sādhanā or austerities are needed."
