Third week after enlightenment Lord Buddha spent one week in walking
meditation. On theplatform lotuses indacate the places where the Lords
feet rested while walking.
In the third week, the Buddha saw through his minds eye that the devas
in the heavens were not sure whether he had attained enlightenment or not.
To prove his enlightenment the Buddha created a golden bridge in the air
and walked up and down it for a whole week.
