At Bodh Gaya, in the modern Indian state of Bihar, Siddhartha Gautama sat beneath a sacred fig (Ficus religiosa) and began to meditate. After training in this meditation for six years.
When his mind was purified by concentration, it is said he acquired the Three Knowledge. The first knowledge was that of his past lives and the past lives of all beings. The second knowledge was of the laws of karma. The third knowledge was that he was free of all obstacles and released from attachments.
Mara wished to stop Siddhartha’s quest for enlightenment, so he brought his most beautiful daughters to seduce him. But Siddhartha did not move. Then Mara sent armies of demons to attack him. Still Siddhartha sat still, and untouched calmly. Then, Mara claimed that the seat of enlightenment rightfully belonged to him and not to a mortal.
In the end, Just before achieving enlightenment, the Mara challenged Siddhartha – These my soldiers speak for me. Who will be your testament of achieving your enlightenment? Then Siddhartha reached out his right hand to touch the earth, and said, ‘the earth will be my testament’ and the earth attested by vibrating. Then, Mara disappeared.
And as the morning star rose in the sky, Siddhartha Gautama fully realized enlightenment and became the “Buddha“.
Lesson: Even in such the Deepest trance meditative state, Siddhartha was very much mindful that he was meditating down on Earth and all were just illusions evolved in his mind. What a Mindfulness he had uphold.
