…Kṛṣṇa conscious devotees know very well that this material world is designed by the complete arrangement of the Lord to fulfill all the necessities of life for all living beings, without their having to encroach upon the life or rights of one another. This complete arrangement affords the proper quota of wealth for everyone according to his real needs, and thus everyone may live peacefully according to the principle of plain living and high thinking. Unfortunately, materialists who have neither faith in the plan of God nor any aspiration for higher spiritual development misuse their God-given intelligence only to augment their material possessions. They devise many systems—such as capitalism and materialistic communism—to advance their material position. They are not interested in the laws of God or in a higher goal. Always anxious to fulfill their unlimited desires for sense gratification, they are conspicuous by their ability to exploit their fellow living beings…

atyāhāraḥ prayāsaś ca
prajalpo niyamāgrahaḥ
jana-saṅgaś ca laulyaṁ ca
ṣaḍbhir bhaktir vinaśyati
ati-āhāraḥ—overeating or too much collecting; prayāsaḥ—overendeavouring; ca—and; prajalpaḥ—idle talk; niyama—rules and regulations; āgrahaḥ—too much attachment to (or agrahaḥ—too much neglect of); jana-saṅgaḥ—association with worldly-minded persons; ca—and; laulyam—ardent longing or greed; ca—and; ṣaḍbhiḥ—by these six; bhaktiḥ—devotional service; vinaśyati—is destroyed.
One’s devotional service is spoiled when he becomes too entangled in the following six activities: (1) eating more than necessary or collecting more funds than required; (2) overendeavoring for mundane things that are very difficult to obtain; (3) talking unnecessarily about mundane subject matters; (4) Practicing the scriptural rules and regulations only for the sake of following them and not for the sake of spiritual advancement, or rejecting the rules and regulations of the scriptures and working independently or whimsically; (5) associating with worldly-minded persons who are not interested in Kṛṣṇa consciousness; and (6) being greedy for mundane achievements.
