Knowledge of Kṛṣṇa's Appearances and Activities
There are two forces of nature working in us. By one we decide that in this lifetime we will make spiritual advancement, but at the next moment the other force,  māyā , or illusory energy, says, “What is all this trouble that you’re going to? Just enjoy this life and be easy with yourself.” This tendency to fall into forgetfulness is the difference between God and man. Arjuna is a companion and associate of Kṛṣṇa’s, and whenever Kṛṣṇa appears on any planet, Arjuna also takes birth and appears with Him. When Kṛṣṇa spoke  Bhagavad-gītā  to the sun god, Arjuna was also present with Him. But, being a finite living entity, Arjuna could not remember. Forgetfulness is the nature of the living entity. We cannot even remember what we were doing at this exact time yesterday or a week ago. If we cannot remember this, how is it possible to remember what happened in our previous lives? At this point we may ask how it is that Kṛṣṇa can remember and we cannot, and the answer is that Kṛṣṇa does not change His body.
