Victims of Desire

Sridhara Swami explains that bees are victims of smell, being sometimes being swallowed up at night by flowers; male elephants are victims of sex desire when hunters display female elephant before a large camouflaged pit; deer are victims of sound when their human predators blow a bugle known as a deer call; fish are victims of their sense of taste when they bite the bait on a fisherman's hook; moths are victims of sight when the hurtle at flames that instantly destroy them.

Similarly, human beings are constantly victimized by all five organs of acquisition.

Development of KC is proportional to detachment from maya

It is said that development of Kṛṣṇa consciousness is exhibited by proportionate material detachment, or vairāgya. If one does not separate himself from material enjoyment, it is to be understood that he is not advancing in Kṛṣṇa consciousness. Renunciation in Kṛṣṇa consciousness is so strong that it cannot be deviated by any attractive illusion. One has to perform devotional service in full tapasya, austerity. One should fast on the two Ekādaśī days, which fall on the eleventh day of the waxing and waning moon, and on the birthdays of Lord Kṛṣṇa, Lord Rāma and Caitanya Mahāprabhu. There are many such fasting days.

To perfect one's life

If one wants to perfect his life, he should discharge his prescribed duties for the satisfaction of Kṛṣṇa. One must act in Kṛṣṇa consciousness, for such action will never produce any reaction (animitta-nimittena).

Unless one's mind is fully engaged

Unless one's mind and consciousness are fully engaged in devotional service, there is always the opportunity for the mind to become occupied with desires for sense gratification.

Krishna is the real friend

The only friend is Kṛṣṇa. One should try to raise the consciousness of the conditioned soul to the platform of understanding that Kṛṣṇa is his actual friend. If one makes friendship with Kṛṣṇa, one will never be cheated, and he will get all help needed. Arousing this consciousness of the conditioned soul is the greatest service, not posing oneself as a great friend of another living entity. The power of friendship is limited. Although one claims to be a friend, he cannot be a friend unlimitedly. There are an unlimited number of living entities, and our resources are limited; therefore we cannot be of any real benefit to the people in general. The best service to the people in general is to awaken them to Kṛṣṇa consciousness so that they may know that the supreme enjoyer, the supreme proprietor and the supreme friend is Kṛṣṇa. Then this illusory dream of lording it over material nature will vanish.
