A woman who has no husband declares herself independent, which means that she becomes a prostitute. A prostitute generally dresses herself in various fashions intended to attract a man’s attention to the lower part of her body. Today it has become a much advertised fashion for a woman to go almost naked, covering the lower part of her body only slightly, in order to draw the attention of a man to her private parts for sexual enjoyment. The intelligence engaged to attract a man to the lower part of the body is the intelligence of a professional prostitute. Similarly, the intelligence of a living entity who does not turn his attention toward Kṛṣṇa or the Kṛṣṇa consciousness movement simply changes dresses like a prostitute. What is the benefit of such foolish intelligence? One should be intelligently conscious in such a way that he need no longer change from one body to another.
Karmīs change their professions at any moment, but a Kṛṣṇa conscious person does not change his profession, for his only profession is to attract the attention of Kṛṣṇa by chanting the Hare Kṛṣṇa mantra and living a very simple life, without following daily changes of fashion. In our Kṛṣṇa consciousness movement, fashionable persons are taught to adopt one fashion — the dress of a Vaiṣṇava with a shaved head and tilaka. They are taught to be always clean in mind, dress and eating in order to be fixed in Kṛṣṇa consciousness. What is the use of changing one’s dress, sometimes wearing long hair and a long beard and sometimes dressing otherwise? This is not good. One should not waste his time in such frivolous activities. One should always be fixed in Kṛṣṇa consciousness and take the cure of devotional service with firm determination.
