One should live in the association of Vaiṣṇavas, where the common goal is advancement in Kṛṣṇa consciousness. Especially in the Kali-yuga, if one tries to remain physically isolated from all others the result will be degradation or insanity. Aniketatām means that one should not be intoxicated by the ephemeral satisfaction of one’s “home sweet home,” which will vanish at any moment by the unforeseen circumstances produced by one’s previous activities. In this age it is not actually possible to dress in tree bark in modern cities, nor to wear mere scraps of cloth. Previously, human culture accommodated those practicing tapasya, or penances in the interest of spiritual advancement. In this age, however, the most urgent necessity is for preaching the message of Bhagavad-gītā throughout human society. Therefore, it is recommended that Vaiṣṇavas dress with clean and neat cloth, covering the body decently so that the conditioned souls will not be frightened or repulsed by the severe penances of the Vaiṣṇavas. In the Kali-yuga the conditioned souls are extremely attached to material sense gratification, and extreme austerities are not appreciated, but are instead considered abominable denials of the flesh. Of course, austerity is required for spiritual advancement, but the practical example set by Śrīla Prabhupāda in successfully spreading the Kṛṣṇa consciousness movement was that all material things should be used to attract people to Kṛṣṇa consciousness. Therefore, Vaiṣṇavas may at times adopt ordinary dress to serve the higher principle of distributing Kṛṣṇa consciousness.
