This is what I heard.
At one time the Buddha was staying in the Jeta Grove, near the city of Sravasti.
With him there was a community of 1,250 venerable monks and devoted disciples.
One day before dawn, the Buddha clothed himself, and along with his disciples took up his alms bowl and entered the city to beg for food door to door, as was his custom.
After he had returned and eaten, he put away his bowl and cloak, bathed his feet, and then sat with his legs crossed and body upright upon the seat arranged for him.
He began mindfully fixing his attention in front of himself, while many monks approached the Buddha, and showing great reverence, seated themselves around him.
After a time a most venerable monk named Subhuti, who was sitting in the congregation, rose from his seat.
He uncovered his right shoulder, placed his right knee on the ground, and as he joined his palms together he respectfully bowed and then addressed the Buddha:
"Most Honored One, It is truly majestic how much knowledge and wisdom your monks and disciples have been given through your most inspired teachings! It is remarkable that you look after our welfare so selflessly and so completely."
"Most Honored One, I have a question to ask you. If sons and daughters of good families want to develop the highest, most fulfilled and awakened mind, if they wish to attain the Highest Perfect Wisdom, what should they do to help quiet their drifting minds and help subdue their craving thoughts?"
The Buddha then replied:
"So it is as you say, Subhuti. Monks and disciples have been favored with the highest favor by the Buddha, the monks and disciples have been instructed with the highest instruction by the Buddha. The Buddha is constantly mindful of the welfare of his followers. Listen carefully with your full attention, and I will speak to your question."
"If sons and daughters of good families want to develop the highest, most fulfilled and awakened mind, if they wish to attain the Highest Perfect Wisdom and quiet their drifting minds while subduing their craving thoughts, then they should follow what I am about to say to you. Those who follow what I am about to say here will be able to subdue their discriminative thoughts and craving desires. It is possible to attain perfect tranquility and clarity of mind by absorbing and dwelling on the teachings I am about to give."
Then the Buddha addressed the assembly.
"All living beings, whether born from eggs, from the womb, from moisture, or spontaneously; whether they have form or do not have form; whether they are aware or unaware, whether they are not aware or not unaware, all living beings will eventually be led by me to the final Nirvana, the final ending of the cycle of birth and death. And when this unfathomable, infinite number of living beings have all been liberated, in truth not even a single being has actually been liberated."
"Why Subhuti? Because if a disciple still clings to the arbitrary illusions of form or phenomena such as an ego, a personality, a self, a separate person, or a universal self existing eternally, then that person is not an authentic disciple."
What is being taught here is not that each is not unigue, but that each is a part of the whole. All things are intrinsic to the thinker and the thinker is intrinsic to the all.
