Hare Krsna
Please accept my humble obeisance. All glories to Srila Prabhupada
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Rupa Goswami came on the order of Chaitanya Mahaprabhu to rejuvenate and re-excavate the land of Vrindavan. The Six Goswamis were engaged in the service of Lord Chaitanya for preaching work.
Whatever we are preaching now, it is based on the principles laid down by the Six Goswamis. Narottama Das Thakur has sung,
rupa-raghunatha-pade ha-ibe akuti
kabe hama bujhaba se yuga
