The first dream Queen Trishala had was of an Elephant.
It was a big, tall and impetuous elephant, with four tusks. It
was an auspicious elephant, and was endowed with all the desirable
marks of excellence.
This dream indicated that Queen Trishala would give
birth to a child with exceptionally good character. The four tusk
signified that he would guide the spiritual chariot with its four
components: monks, nuns, laymen and laywomen.
