When we are materially contaminated, we are called conditioned. False consciousness is exhibited under the impression that I am a product of material nature. This is called false ego. One who is absorbed in the thought of bodily conceptions cannot understand his situation. Bhagavad-gītā was spoken to liberate one from the bodily conception of life, and Arjuna put himself in this position in order to receive this information from the Lord. One must become free from the bodily conception of life; that is the preliminary activity for the transcendentalist. One who wants to become free, who wants to become liberated, must first of all learn that he is not this material body. Mukti, or liberation, means freedom from material consciousness. In the Śrīmad-Bhāgavatam also the definition of liberation is given. Muktir hitvānyathā-rūpaṁ svarūpeṇa vyavasthitiḥ: (SB 2.10.6) mukti means liberation from the contaminated consciousness of this material world and situation in pure consciousness. All the instructions of Bhagavad-gītā are intended to awaken this pure consciousness, and therefore we find at the last stage of the Gītā's instructions that Kṛṣṇa is asking Arjuna whether he is now in purified consciousness. Purified consciousness means acting in accordance with the instructions of the Lord. This is the whole sum and substance of purified consciousness. Consciousness is already there because we are part and parcel of the Lord, but for us there is the affinity of being affected by the inferior modes. But the Lord, being the Supreme, is never affected. That is the difference between the Supreme Lord and the small individual souls.
What is this consciousness? This consciousness is "I am." Then what am I? In contaminated consciousness "I am" means "I am the lord of all I survey. I am the enjoyer." The world revolves because every living being thinks that he is the lord and creator of the material world. Material consciousness has two psychic divisions. One is that I am the creator, and the other is that I am the enjoyer. But actually the Supreme Lord is both the creator and the enjoyer, and the living entity, being part and parcel of the Supreme Lord, is neither the creator nor the enjoyer, but a cooperator. He is the created and the enjoyed. For instance, a part of a machine cooperates with the whole machine; a part of the body cooperates with the whole body. The hands, legs, eyes, and so on are all parts of the body, but they are not actually the enjoyers. The stomach is the enjoyer. The legs move, the hands supply food, the teeth chew, and all parts of the body are engaged in satisfying the stomach because the stomach is the principal factor that nourishes the body's organization. Therefore everything is given to the stomach. One nourishes the tree by watering its root, and one nourishes the body by feeding the stomach, for if the body is to be kept in a healthy state, then the parts of the body must cooperate to feed the stomach. Similarly, the Supreme Lord is the enjoyer and the creator, and we, as subordinate living beings, are meant to cooperate to satisfy Him. This cooperation will actually help us, just as food taken by the stomach will help all other parts of the body. If the fingers of the hand think that they should take the food themselves instead of giving it to the stomach, then they will be frustrated. The central figure of creation and of enjoyment is the Supreme Lord, and the living entities are cooperators. By cooperation they enjoy. The relation is also like that of the master and the servant. If the master is fully satisfied, then the servant is satisfied. Similarly, the Supreme Lord should be satisfied, although the tendency to become the creator and the tendency to enjoy the material world are there also in the living entities because these tendencies are there in the Supreme Lord who has created the manifested cosmic world.
We shall find, therefore, in this Bhagavad-gītā that the complete whole is comprised of the supreme controller, the controlled living entities, the cosmic manifestation, eternal time and karma, or activities, and all of these are explained in this text. All of these taken completely form the complete whole, and the complete whole is called the Supreme Absolute Truth. The complete whole and the complete Absolute Truth are the complete Personality of Godhead, Śrī Kṛṣṇa. All manifestations are due to His different energies. He is the complete whole.
It is also explained in the Gītā that impersonal Brahman is also subordinate to the complete Supreme Person (brahmaṇo hi pratiṣṭhāham). Brahman is more explicitly explained in the Brahma-sūtra to be like the rays of the sunshine. The impersonal Brahman is the shining rays of the Supreme Personality of Godhead. Impersonal Brahman is incomplete realization of the absolute whole, and so also is the conception of Paramātmā. In the Fifteenth Chapter it shall be seen that the Supreme Personality of Godhead, Puruṣottama, is above both impersonal Brahman and the partial realization of Paramātmā. The Supreme Personality of Godhead is called sac-cid-ānanda-vigraha. The Brahma-saṁhitā begins in this way: īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ/ anādir ādir govindaḥ sarva-kāraṇa-kāraṇam. "Govinda, Kṛṣṇa, is the cause of all causes. He is the primal cause, and He is the very form of eternity, knowledge and bliss." Impersonal Brahman realization is the realization of His sat (eternity) feature. Paramātmā realization is the realization of sat-cit (eternal knowledge). But realization of the Personality of Godhead, Kṛṣṇa, is realization of all the transcendental features: sat, cit and ānanda (eternity, knowledge, and bliss) in complete vigraha (form).
