yāre dekha, tāre kaha 'kṛṣṇa'-upadeśa āmāra ājñāya guru hañā tāra' ei deśa

(Cc. Madhya 7.128)

It is Sri Caitanya Mahaprabhu's wish that everyone should become a Vaisnava and guru. Following the instructions of Sri Caitanya Mahaprabhu and His disciplic succession, one can become a spiritual master, for the process is very easy. One can go everywhere and anywhere to preach the instructions of Krsna. Bhagavad-gita is Krsna's instructions; therefore the duty of every Vaisnava is to travel and preach Bhagavad-gita, either in his country or a foreign country. This is the test of sparsa-mani, following in the footsteps of Narada Muni.
