Wat Phra Pathom Chedi : Buddha Images (7)

Receiving a Mango
While in the yoga posture, the Buddha has his right hand positioned on the knee, holding a mango.
The Buddha performed a miracle while staying at Veluvana. Some heretics 'demanded' a miracle for him to prove his powers.
The Buddha pressed the mango into a bowl, drank the juice, then had the mango seed planted. Immediately, a large tree grew, with plenty of fruit.
[Preaching at Sarnath]
