The Bodhisattva was born neither in India nor in Nepal. And also he didn’t attain Buddhahood in India.
The real Shakya kingdom was neither in India nor in Nepal. It was in Sri Lanka. The Sinhala people are the direct descendants of the Shakya dynasty (in which the Bodhisattva was born). The Sinhalese people are the Shakya Putras.
Just as the hidden meaning of the critical concepts in Tipitaka had been hidden for many centuries, similarly the real places associated with Lord Buddha’s life was also forgotten. It will be hard to believe for many but the truth is that the Bodhisattva was born in Sri Lanka and he attained Samma Sambodhi in Anuradhapura, Sri Lanka sitting under Jaya Sri Maha Bodhi !!!
Most Ven. Waharaka Thero had confirmed this fact. A person with a special kind of Samadhi can experience the “Immeasurable and Pure Buddha Energy” continuously radiating from Jaya Sri Maha Bodhi in Anuradhapura even today. That is the biggest proof !
The Maitreya Bodhisattva (Future Buddha) will also attain Samma Sambodhi at the very same place. There is no other place on Earth where it can happen.
