Lord Caitanya teaches the science of Kṛṣṇa consciousness. That science is absolute. Dry mental speculators try to restrain themselves from material attachment, but it is generally found that the mind is too strong to be controlled and that it drags them down to sensual activities. A person in Kṛṣṇa consciousness does not run this risk. One therefore has to engage one's mind and senses in Kṛṣṇa conscious activities, and Lord Caitanya teaches one how to do this in practice.
Before accepting sannyāsa (the renounced order), Lord Caitanya was known as Viśvambhara. The word viśvambhara refers to one who maintains the entire universe and who leads all living entities. This maintainer and leader appeared as Lord Śrī Kṛṣṇa Caitanya to give humanity these sublime teachings. Lord Caitanya is the ideal teacher of life's prime necessities. He is the most munificent bestower of love of Kṛṣṇa. He is the complete reservoir of all mercies and good fortune. As confirmed in Śrīmad-Bhāgavatam, the Bhagavad-gītā, the Mahābhārata and the Upaniṣads, He is the Supreme Personality of Godhead, Kṛṣṇa Himself, and He is worshipable by everyone in this age of disagreement. Everyone can join in His saṅkīrtana movement. No previous qualification is necessary. Just by following His teachings, anyone can become a perfect human being. If a person is fortunate enough to be attracted by Lord Caitanya, he is sure to be successful in his life's mission. In other words, those who are interested in attaining spiritual existence can easily be released from the clutches of māyā by the grace of Lord Caitanya. The teachings presented in this book are nondifferent from the Lord.
The conditioned soul, engrossed in the material body, increases the pages of history by all kinds of material activities. The teachings of Lord Caitanya can help the members of human society stop such unnecessary and temporary activities and be elevated to the topmost platform of spiritual activities, which begin after liberation from material bondage. Such liberated activities in Kṛṣṇa consciousness constitute the goal of human perfection. The false prestige one acquires by attempting to dominate material nature is illusory. Illuminating knowledge can be acquired by studying the teachings of Lord Caitanya, and by such knowledge one can advance in spiritual existence.
Everyone has to suffer or enjoy the fruits of his activity; no one can check the laws of material nature that govern such things. As long as one is engaged in fruitive activity, one is sure to be baffled in the attempt to attain the ultimate goal of life. I sincerely hope that by understanding the teachings of Lord Caitanya presented in this book, Śrī Caitanya-caritāmṛta, human society will experience a new light of spiritual life, which will open the field of activity for the pure soul.
