What is the bodhi and how can it be achieved?―a teaching form Vimalakīrtinirdesa Chapter 3. 48-53

1. What is the bodhi?

The bodhi is the ultimate goal all Buddhism trainees long. The Buddha claims "I once was a bodhisattva, but I become a buddha with achieving the saṃbodhi(bodhi-completion)". On Vimalakīrtinirdeṣa §3.48-53, Vimalakīrti gives a teaching on what the bodhi is, and how can it achieved from the Mahāyāna Buddhism perspective. (Vimalakīrtinirdeṣa full text is downloadable here).

2. Context of the Vimalakīrtinirdeṣa §3.48-53

The story is about the Buddha and his apprentices talking about visiting Vimalakīrti lying down on the bed because people troubles hit him. On Chap.3, the apprentices are told by the Buddha to go visit Vimalakīrti and they refuse. On §48-53, the Maitreya Boddhisattva is told to go but refuses.

3. Maitreya's excuse

3.1 Maitreya was once under the Vimalakīrti's attack §3.48-52

Maitreya also said "Blessed one, I'm reluctant to go visit him. It is because, I remember that the time when I was teaching the dharma with gods' sons of heavenly Tusita about the bodhisattvas' never-look-back mindsets. At that time, Vimalakīrti came there and told me. 'Oh Maitreya, you are prophesied to become a buddha.  ... Your tathāta is every living creature's tathāta, if you are prophesied to become a buddha, every creature is prophesied to become a buddha. But how can you achive a buddha? ... the bodhi is indeed every creature achiving the bodhi. So Maitreya, your achiving the nirvana means every creature achiving the nirvana. Forget your plan of gods' sons' achieving the bodhi.'

So Maitreya, abandant your wrongful thought about the Bodhi.

The Bodhi is... '"

3.2 Explanation: Why Vimalakīrti attacked? (The answer is the Mahāyāna Buddhism.)

Maitreya is a famous character in Buddhism who is described as a promised one to become a buddha one day. On this Sutra, he said to the Buddha that he'd tried to bring his friends, the gods' sons of heavenly Tusita, to the nirvana, but Vimalakīrti had argued back his idea. 

As I described in here, everything is considered to be interdependently connected in the Mahāyāna Buddhism teaching. Even Maitreya, the chosen one, is not exceptional his tathāta(true nature) depends on the others' tathāta. 

In conclusion while every creature doesn't achieve the nirvana, Maitreya (and his friends) can't achieve the nirvana, and be a buddha.

3.3 So what is the bodhi? §3.53

4. Maitreya's conclusion 

Translation by Google Gemini.

O Venerable One, when this instruction was being given, two hundred sons of gods in that assembly attained the forbearance with respect to the non-origination of things. But I was left without a counterpart (or was speechless). Therefore, O Venerable One, I am not capable of going to inquire about the illness of that good person.
