When Krsna appeared as the son of Vasudeva and Devaki, He first of all appeared as four-armed Narayana, but when He was requested by His parents, He transformed Himself into an ordinary child in appearance. Similarly, Krsna knew that Arjuna was not interested in seeing a four-handed form of Krsna, but since he asked to see this four-handed form, He also showed him this form again and then showed Himself in His two-handed form. The word saumya-vapuh is very significant. Saumya-vapu is a very beautiful form; it is known as the most beautiful form. When He was present, everyone was attracted simply by Krsna's form, and because Krsna is director of the universe, He just banished the fear of Arjuna, His devotee, and showed him again His beautiful form of Krsna. In the Brahma-samhita it is stated that only a person whose eyes are smeared with the ointment of love can see the beautiful form of Sri Krsna.
