A living being's constitutional position is to render service, but in the atmosphere of māyā, or illusion, or the conditional state of existence, the conditioned soul seeks the service of illusion.
(Srimad Bhagavatam-----2:2:6-----purport).

The well-situated self, or Brahman-realized soul, perfectly understands that the Supreme Brahman, or the Personality of Godhead, is the all-powerful Vāsudeva and that he (the self-realized living being) is a part and parcel of the supreme whole. As such, his constitutional position is to cooperate with Him in all respects in the transcendental relation of the served and the servitor. Such a self-realized soul ceases to exhibit his useless activities of attempting to lord it over material nature. Being scientifically well informed, he fully engages himself in faithful devotion to the Lord.
(Srimad Bhagavatam-----2:2:19-----purport).

The whole process of spiritual culture is aimed at changing the heart of the living being in the matter of his eternal relation with the Supreme Lord as subordinate servant, which is his eternal constitutional position.
(Srimad Bhagavatam-----2:2:24-----purport).

A living entity, by his constitutional position, cannot be void of all desires (the bhukti-kāmī, mukti-kāmī and siddhi-kāmī all desire something for personal satisfaction), but the niṣkāmī devotees of the Lord desire everything for the satisfaction of the Lord. They are completely dependent on the orders of the Lord and are always ready to discharge their duty for the satisfaction of the Lord.
(Srimad Bhagavatam-----2:4:19-----purport).

To be instrumental to the direct will of the Lord is the natural constitutional position of the living entity, whereas to be an instrument in the hands of the illusory energy of the Lord is material bondage for the living entity.
(Srimad Bhagavatam-----2:9:29-----purport).

A pure living entity in his original spiritual existence is fully conscious of his constitutional position as an eternal servitor of the Lord. All souls who are situated in such pure consciousness are liberated, and therefore they eternally live in bliss and knowledge in the various Vaikuṇṭha planets in the spiritual sky.
(Srimad Bhagavatam-----3:5:29-----purport).

The chief function of the false ego is godlessness. When a person forgets his constitutional position as an eternally subordinate part and parcel of the Supreme Personality of Godhead and wants to be happy independently, he functions mainly in two ways. He first attempts to act fruitively for personal gain or sense gratification, and after attempting such fruitive activities for a considerable time, when he is frustrated he becomes a philosophical speculator and thinks himself to be on the same level as God. This false idea of becoming one with the Lord is the last snare of the illusory energy, which traps a living entity into the bondage of forgetfulness under the spell of false ego.
(Srimad Bhagavatam-----3:5:31-----purport).

The Lord creates this material world and impregnates the material energy with the living entities who will act in the material world. All these actions have a divine plan behind them. The plan is to give the conditioned souls who so desire a chance to enjoy sense gratification. But there is another plan behind the creation: to help the living entities realize that they are created for the transcendental sense gratification of the Lord and not for their individual sense gratification. This is the constitutional position of the living entities.
(Srimad Bhagavatam-----3:5:51-----purport).

Since they are born from different parts of the body of the Supreme Lord in His gigantic form, all living entities in all parts of the entire universe are supposed to be eternal servitors of the supreme body. Every part of our own body, such as the mouth, hands, thighs and legs, is meant to render service to the whole. That is their constitutional position. In subhuman life the living entities are not conscious of this constitutional position, but in the human form of life they are supposed to know this through the system of the varṇas, the social orders. As above mentioned, the brāhmaṇa is the spiritual master of all the orders of society, and thus brahminical culture, culminating in the transcendental service of the Lord, is the basic principle for purifying the soul.
(Srimad Bhagavatam-----3:6:34-----purport).

The whole trouble of the living entity in material existence is that he has an independent conception of life. He is always dependent on the rules of the Supreme Lord, in both the conditioned and liberated states, but by the influence of the external energy the conditioned soul thinks himself independent of the supremacy of the Personality of Godhead. Hisconstitutional position is to dovetail himself with the desire of the supreme will, but as long as he does not do so, he is sure to drag on in the shackles of material bondage.
(Srimad Bhagavatam-----3:9:9-----purport).

The conditioned souls, or living entities who come to the material world to enjoy sense gratification, are covered in the beginning by five different conditions. The first condition is a covering of tāmisra, or anger. Constitutionally, each and every living entity has minute independence; it is misuse of that minute independence for the conditioned soul to think that he can also enjoy like the Supreme Lord or to think, "Why shall I not be a free enjoyer like the Supreme Lord?" This forgetfulness of his constitutional position is due to anger or envy. The living entity, being eternally a part-and-parcel servitor of the Supreme Lord, can never, by constitution, be an equal enjoyer with the Lord.
(Srimad Bhagavatam-----3:20:18-----purport).

When one engages in the transcendental devotional service of the Lord one becomes aware that his constitutional position, as an individual soul, is to be eternally a servitor of the Supreme Lord, Vāsudeva. Self-realization does not mean that because the Supreme Soul and the individual soul are both souls they are equal in every respect. The individual soul is prone to be conditioned, and the Supreme Soul is never conditioned.
(Srimad Bhagavatam-----3:24:45-----purport).

As soon as the living entity forgets his real, constitutional position of eternal servitorship to the Lord and wants instead to enjoy himself by sense gratification, he is captured by māyā. This capture by māyā is the consciousness of false identification with the body and attachment for the possessions of the body. These are the activities of māyā, and since māyā is also an agent of the Lord, it is indirectly the action of the Lord.
(Srimad Bhagavatam-----3:25:10-----purport).

Unless one is interested in understanding his spiritual life, or his constitutional position, and unless he also feels inconvenience in material existence, his human form of life is spoiled. One who does not care for these transcendental necessities of life and simply engages like an animal in eating, sleeping, fearing and mating has spoiled his life.
(Srimad Bhagavatam-----3:25:12-----purport).

No one can separate the molecular parts of the sunshine from the sun, but at the same time the molecular part of the sunshine is not as expansive as the sun itself. Similarly, the living entity, by his constitutional position, is qualitatively the same as the Supreme Spirit, but he is infinitesimal.
(Srimad Bhagavatam-----3:25:17-----purport).

One understands his constitutional position by knowledge and vairāgya, renunciation. Without knowledge, one cannot have realization. The realization that one is the infinitesimal part and parcel of the Supreme Spirit makes him unattached to material, conditional life. That is the beginning of devotional service. Unless one is liberated from material contamination, one cannot engage himself in the devotional service of the Lord. In this verse, therefore, it is stated, jñāna-vairāgya-yuktena: when one is in full knowledge of one'sconstitutional position and is in the renounced order of life, detached from material attraction, then, by pure devotional service, bhakti-yuktena, he can engage himself as a loving servant of the Lord.
(Srimad Bhagavatam-----3:25:18-----purport).
