Among the demigods Lord Krishna appears in such forms as Vamanadeva, among the sages as Parasurama, among human beings as Lord Krishna Himself and as Lord Ramacandra, and among animals as the boar incarnation. Lord Krishna appears among the aquatics as Matsya, the gigantic fish. Indeed, the plenary expansions of the Supreme Personality of Godhead are innumerable, as the Lord relentlessly comes down within the universes to smash the false pride of the atheists and show mercy to the saintly devotees.
In another sense, the Lord never appears, since He exists eternally. His appearance is like that of the sun, which is always present in the sky but which periodically appears to our vision.
