An imperfect living being does not even know what is happening within his own personal body. He eats his food but does not know how this food is transformed into energy or how it sustains his body. When a living being is perfect, he is aware of everything that happens, and since the Supreme Person is all-perfect, it is quite natural that He knows everything in all detail. Consequently the perfect personality is addressed in the Śrīmad-Bhāgavatam as Vāsudeva, or one who lives everywhere in full consciousness and in full possession of His complete energy. All of this is clearly explained in the Śrīmad-Bhāgavatam, and the reader has ample opportunity to study this critically.
In the modern age Lord Śrī Caitanya Mahāprabhu preached the Śrīmad-Bhāgavatam by practical demonstration. It is easier to penetrate into the topics of the Śrīmad-Bhāgavatam through the medium of Śrī Caitanya's causeless mercy. Therefore a short sketch of His life and precepts is inserted herein to help the reader understand the real merit of Śrīmad-Bhāgavatam.
It is imperative that one learn the Śrīmad-Bhāgavatam from the person Bhāgavatam. The person Bhāgavatam is one whose very life is Śrīmad-Bhāgavatam in practice. Since Śrī Caitanya Mahāprabhu is the Absolute Personality of Godhead, He is both Bhagavān and Bhāgavatam in person and in sound. Therefore His process of approaching the Śrīmad-Bhāgavatam is practical for all people of the world. It was His wish that the Śrīmad-Bhāgavatam be preached in every nook and corner of the world by those who happened to take their birth in India.
