While Lord Krishna continues -in Chapter 11 of The Gita- to overwhelm us with His all encompassing splendor, His wonderful form becomes terrible. Arjun sees that all space between heaven and earth is filled by God and that all worlds are frightened.
In this scary appearance representing Kala or Time, God demonstrates karma in process. Warriors, already doomed, rush into the Lord’s multiple mouths like
moths flying into a blazing fire. The Lord assures Arjun that he will prevail in this Great Mahabharata War.
Arjun begs God to reappear in His calm, gentle four armed form, a form which can be seen, Lord Krishna says, through endless love of Him.
Chapter 11 is one of the most dramatic chapters of the Gita. It illustrates not only the ideas, hopes and fears that human beings entertain about their Creator, but also our more sophisticated understanding of dimensions and of the confluenced integration of universes, time and space.
