Very strong (CC)
Sri Caitanya-caritamrta
CC Adi-lila
CC Adi 3.34, Purport:
During the time of Lord Caitanya, the influence of Śaṅkarācārya in society was very strong. People thought that one could accept sannyāsa only in the disciplic succession of Śaṅkarācārya. Lord Caitanya could have performed His missionary activities as a householder, but He found householder life an obstruction to His mission. Therefore He decided to accept the renounced order, sannyāsa. Since His acceptance of sannyāsa was also designed to attract public attention, Lord Caitanya, not wishing to disturb the social convention, took the renounced order of life from a sannyāsī in the disciplic succession of Śaṅkarācārya, although sannyāsa was also sanctioned in the Vaiṣṇava sampradāya.
