The Supreme Lord, the Absolute Personality of Godhead, Śrī Kṛṣṇa, although equal to everyone, is still more inclined to His unflinching devotee who is completely surrendered and knows no one else as his protector and master. Having unflinching faith in the Supreme Lord as one's protector, friend and master is the natural condition of eternal life. A living entity is so made by the will of the Almighty that he is most happy when placing himself in a condition of absolute dependence.
The opposite tendency is the cause of falldown. The living entity has this tendency of falling down by dint of misidentifying himself as fully independent to lord it over the material world. The root cause of all troubles is there in false egotism. One must draw towards the Lord in all circumstances.
(Srimad Bhagavatam---1:9:22---purport).

The example given here is very appropriate. If a big lake is covered all around by long kuśa grass, just like columns, the waters dry up. Similarly, when the big columns of material desire increase, the clear water of consciousness is dried up. Therefore these columns of kuśa grass should be cut or thrown away from the very beginning. Śrī Caitanya Mahāprabhu has instructed that if from the very beginning we do not take care of unwanted grass in the paddy fields, the fertilizing agents or water will be used by them, and the paddy plants will dry up. The material desire for sense enjoyment is the cause of our falldown in this material world, and thus we suffer the threefold miseries and continuous birth, death, old age and disease. However, if we turn our desires toward the transcendental loving service of the Lord, our desires become purified. We cannot kill desires. We have to purify them of different designations. If we constantly think of being a member of a particular nation, society or family and continuously think about them, we become very strongly entangled in the conditioned life of birth and death. But if our desires are applied to the service of the Lord, they become purified, and thus we become immediately freed from material contamination.
(Srimad Bhagavatam---4:22:30---purport).

Here it is clearly stated: haṁso haṁsena pratibodhitaḥ. The individual soul and the Supersoul are both compared to swans (haṁsa) because they are white, or uncontaminated. One swan, however, is superior and is the instructor of the other. When the inferior swan is separated from the other swan, he is attracted to material enjoyment. This is the cause of his falldown. When he hears the instructions of the other swan, he understands his real position and is again revived to his original consciousness. The Supreme Personality of Godhead, Kṛṣṇa, comes down (avatāra) to deliver His devotees and kill the demons. He also gives His sublime instructions in the form of Bhagavad-gītā. The individual soul has to understand his position by the grace of the Lord and the spiritual master because the text of Bhagavad-gītā cannot be understood simply by academic qualifications. One has to learn Bhagavad-gītā from a realized soul.
