The symptoms of the mind are determination and rejection, which are due to different kinds of desires. We desire that which is favorable to our sense gratification, and we reject that which is not favorable to sense gratification. The material mind is not fixed, but the very same mind can be fixed when engaged in the activities of Kṛṣṇa consciousness. Otherwise, as long as the mind is on the material platform, it is hovering, and all this rejection and acceptance is asat, temporary. It is stated that he whose mind is not fixed in Kṛṣṇa consciousness must hover between acceptance and rejection. However advanced a man is in academic qualifications, as long as he is not fixed in Kṛṣṇa consciousness he will simply accept and reject and will never be able to fix his mind on a particular subject matter.

By false ego all material things are produced as objects of enjoyment. One has to cease increasing artificial necessities in the form of material objects. One great ācārya, Narottama dāsa Ṭhākura, has lamented that when one deviates from pure consciousness of Vāsudeva, or Kṛṣṇa consciousness, he becomes entangled in material activities.

In the beginning, from clear consciousness, or the pure state of Kṛṣṇa consciousness, the first contamination sprang up. This is called false ego, or identification of the body as self. The living entity exists in the natural state of Kṛṣṇa consciousness, but he has marginal independence, and this allows him to forget Kṛṣṇa. Originally, pure Kṛṣṇa consciousness exists, but because of misuse of marginal independence there is a chance of forgetting Kṛṣṇa. This is exhibited in actual life; there are many instances in which someone acting in Kṛṣṇa consciousness suddenly changes.

The pure status of consciousness, or Kṛṣṇa consciousness, exists in the beginning; just after creation, consciousness is not polluted. The more one becomes materially contaminated, however, the more consciousness becomes obscured. In pure consciousness one can perceive a slight reflection of the Supreme Personality of Godhead. As in clear, unagitated water, free from impurities, one can see everything clearly, so in pure consciousness, or Kṛṣṇa consciousness, one can see things as they are. One can see the reflection of the Supreme Personality of Godhead, and one can see his own existence as well. This state of consciousness is very pleasing, transparent and sober. In the beginning, consciousness is pure.

The vāsudeva manifestation, or the status of understanding the Supreme Personality of Godhead, is called pure goodness, or śuddha-sattva. In the śuddha-sattva status there is no infringement of the other qualities, namely passion and ignorance. In the Vedic literature there is mention of the Lord’s expansion as the four Personalities of Godhead — Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha. Here in the reappearance of the mahat-tattva the four expansions of Godhead occur.

Since the Supreme Personality of Godhead is ever existing, all-blissful and full of knowledge, His different energies are also ever existing in the dormant stage. Thus when the mahat-tattva was created, it manifested the material ego and swallowed up the darkness which covered the cosmic manifestation at the time of dissolution. This idea can be further explained. A person at night remains inactive, covered by the darkness of night, but when he is awakened in the morning, the covering of night, or the forgetfulness of the sleeping state, disappears. Similarly, when the mahat-tattva appears after the night of dissolution, the effulgence is manifested to exhibit the variegatedness of this material world.

It is described in the Viṣṇu Purāṇa that the living entities belong to the spiritual nature. The potency of the Supreme Lord is spiritual, and the living entities, although they are called marginal potency, are also spiritual. If the living entities were not spiritual, this description of impregnation by the Supreme Lord would not be applicable.

The living entity is constitutionally part and parcel of the Supreme Personality of Godhead, the Lord is very affectionate to the living entities. Unfortunately, when the living entity is bewildered or illusioned by the external energy, he becomes forgetful of his eternal relationship with the Lord, but as soon as he becomes aware of his constitutional position, he is liberated.

The unmanifested state of material nature, pradhāna, is being explained. The Lord says that when the unmanifested material nature is agitated by the glance of the Supreme Personality of Godhead, it begins to manifest itself in different ways. Before this agitation, it remains in the neutral state, without interaction by the three modes of material nature. In other words, material nature cannot produce any variety of manifestations without the contact of the Supreme Personality of Godhead. This is very nicely explained in Bhagavad-gītā. The Supreme Personality of Godhead is the cause of the products of material nature. Without His contact, material nature cannot produce anything.

The living entity’s fear of death is due to his false ego of identifying with the body. Everyone is afraid of death. Actually there is no death for the spirit soul, but due to our absorption in the identification of body as self, the fear of death develops.
