Śrīmad-Bhāgavatam
[Canto 4, Ch. 27]
TRANSLATION
Approaching the King of the Yavanas, Kālakanyā addressed him as a great hero, saying: My dear sir, you are the best of the untouchables. I am in love with you, and I want you as my husband. I know that no one is baffled if he makes friends with you.
PURPORT
The words  yavanānām rṣabham  refer to the King of the Yavanas. The Sanskrit words  yavana  and  mleccha  apply to those who do not follow the Vedic principles. According to the Vedic principles, one should rise early in the morning, take bath, chant Hare Krṣṇa, offer  maṅgala-ārati  to the Deities, study Vedic literature, take  prasāda , and engage in dressing and decorating the Deities. One must also collect money for the temple expenditures, or if one is a householder he must go to work in accordance with the prescribed duties of a  brāhmaṇa ,  kṣatriya ,  vaiśya  or  śūdra . In this way one should live a life of spiritual understanding, and this is the Vedic way of civilization. One who does not follow all these rules and regulations is called a  yavana  or  mleccha . One should not mistakenly think that these words refer to certain classes of men in other countries. There is no question of limitation according to nationalism. Whether one lives in India or outside of India, he is called a  yavana  or  mleccha  if he does not follow the Vedic principles. One who does not actually follow the hygienic principles prescribed in the Vedic rules and regulations will be subjected to many contagious diseases. Because the students in this Krṣṇa consciousness movement are advised to follow the Vedic principles, they naturally become hygienic.
If a person is Krṣṇa conscious, he can work like a young man even if he is seventy-five or eighty years old. Thus the daughter of Kāla (time) cannot overcome a Vaiṣṇava. Śrīla Krṣṇadāsa Kavirāja Gosvāmī engaged in writing  Caitanya-caritāmṛta  when he was very old, yet he presented the most wonderful literature of the activities of Lord Caitanya. Śrīla Rūpa Gosvāmī and Sanātana Gosvāmī began their spiritual lives at a very old age, that is, after they retired from their occupations and family lives. Yet they presented many valuable literatures for the advancement of spiritual life. This is confirmed by Śrīla Śrīnivāsa Ācārya, who praised the Gosvāmīs in this way:
nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau lokānāṁ hita-kāriṇau tri-bhuvane mānyau śaraṇyākarau
