SB 1.6 - Experiencing all varieties of God's creation
Nārada passed thru hills and mountains full of minerals like gold, silver and copper, and thru tracts of land with reservoir of water filled with beautiful lotus flowers decorated with bees and singing birds. He then passed thru many forests of rushes, bamboo, sharp grass, weeds and caves, which were difficult to pass thru alone. He visited deep, dark and dangerous forests, which were the play yards of snakes, owls and jackals. It is the duty of a mendicant to experience all varieties of God’s creation by traveling alone thru all forests, hills, towns and villages to gain faith in God and strength of mind as well as to enlighten the inhabitants with the message of God. Wandering without external shelter increases one’s dependence on Kṛṣṇa because it tests and strengthens one’s faith. One begins to realize fearlessness. Nārada was absorbed in tasting the sweetness of the Lord and so did not experience surprise or fear.
A sannyāsī is duty bound to take all risks without fear, and the most typical sannyāsī of the present age is Lord Caitanya, who traveled in the same manner thru the jungles. One should take the vow to stop social intercourse completely and devote life exclusively to the service of the Lord. In this age, devotional service of hearing and chanting the holy glories of the Lord is recommended, and one need not imitate the parivrājakācārya like Nārada or Caitanya, but may sit down at some holy place and devote his time to hear and repeatedly chant the holy scriptures left by great ācāryas like the six Gosvāmīs of Vṛndāvana.
