Furthermore, because all sentient beings are oppressed by the suffering of birth, they move about within the womb from place to place. Not so the Bodhisattva: he entered from the right side and remained in the right side; while in the womb he never moved. And when he was about to emerge, he was born from the right side, without being pressed or afflicted by the host of sufferings. This was an unprecedented event of the Bodhisattva. It symbolizes that after achieving buddhahood, through the end of the ultimate future, in practicing the brahmacarya he would be forever without fear, constantly obtaining joy, free from any further sufferings.
