Acyuta. Kṛṣṇa is not cyuta. Kṛṣṇa is acyuta. Cyuta means those who are fallen in the material world. They are cyuta. We are fallen in the material world. Therefore we have accepted this material body. Icchā-dveṣa-samutthena sarge yānti parantapa (B.G. 7:27). Icchā. Icchā means desire. And dveṣa means envy, enviousness. Icchā-dveṣa-samutthena. When we become envious of Kṛṣṇa and we want to enjoy this material world, then we come to this material creation. Icchā-dveṣa-samutthena sarge yānti parantapa.
(Lecture on Bhagavad-Gita--2:1--Ahmedabad--6th. December, 1972).

One who is conducted by false ego and thus always distressed, both mentally and sensually, cannot tolerate the opulence of self-realized persons. Being unable to rise to the standard of self-realization, he envies such persons as much as demons envy the Supreme Personality of Godhead.
(Srimad Bhagavatam--4:3:21--purport).

In the material world everyone who comes to enjoy himself or lord it over material nature is envious of others. This envy is also found in the personality of the King of heaven, Indra. As evident from revealed scriptures, Indra was several times envious of many persons.
(Srimad Bhagavatam--4:19:2--purport).

In the material world everyone is envious of his fellow man. Animalistic envy exists in human society as long as there is no performance of saṅkīrtana-yajña, the chanting of the holy names—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
(Srimad Bhagavatam--4:30:35--purport).

In this material world everyone is envious of everyone else, but by vibrating or discussing the holy name of the Lord, one becomes nonenvious and devoid of material hankering. Because of our envy of the Supreme Personality of Godhead, we have become envious of all other living entities. When we are no longer envious of the Supreme Personality of Godhead, there will be real peace, unity and fraternity in human society.
Srimad Bhagavatam--4:30:36--purport).

This material world is simply an embarrassment and is composed of tribulations presented as happiness, distress, attachment, enmity and envy. On the whole it is simply full of tribulation and misery.
(Srimad Bhagavatam--5:14--summary).

A person who is unaffected by attachment and envy is said to possess equilibrium. (Nectar of Devotion).

When one becomes malicious upon seeing another's advancement of life, his state of mind is generally called envy. (Nectar of Devotion).

Devotees have no need to compete with materialists because they are on the path back to Godhead, back home where everything is eternal, full and blissful. Such transcendentalists are a hundred percent nonenvious and are therefore pure in heart. Because everyone in the material world is envious, there is competition. The devotees of the Lord are not only free from all material envy, but they are also kind to everyone in an attempt to establish a competitionless society with God in the center.
