Accepting some of the scriptural rules and regulations for immediate benefit, as utilitarians advocate, is called niyama-āgraha, and neglecting the rules and regulations of the śāstras, which are meant for spiritual development, is called niyama-agraha. The word āgraha means “eagerness to accept,” and agraha means “failure to accept.” By the addition of either of these two words to the word niyama (“rules and regulations”), the word niyamāgraha is formed. Thus niyamāgraha has a twofold meaning that is understood according to the particular combination of words. Those interested in Kṛṣṇa consciousness should not be eager to accept rules and regulations for economic advancement, yet they should very faithfully accept scriptural rules and regulations for the advancement of Kṛṣṇa consciousness. They should strictly follow the regulative principles by avoiding illicit sex, meat-eating, gambling and intoxication.
One should also avoid association with Māyāvādīs, who simply blaspheme Vaiṣṇavas (devotees). Bhukti-kāmīs, who are interested in material happiness, mukti-kāmīs, who desire liberation by merging in the existence of the formless Absolute (Brahman), and siddhi-kāmīs, who desire the perfection of mystic yoga practice, are classified as atyāhārīs. To associate with such persons is not at all desirable.
