Vimalakirti than asked Manjushri, “What may act as the seeds of the Tathagata?”
Manjushri said, “The body is the seed, ignorance and partiality are the seeds, greed, anger, and stupidity are the seeds. The four inverted views are the seeds, the five obscurations are the seeds, the six sense-media are the seeds, the seven abodes of consciousness are the seeds, the eight errors are the seeds, the nine sources of anxiety are the seeds, the ten evil actions are the seeds. To sum it up, the sixty-two erroneous views and all the different kinds of earthly desires are all the seeds of the Buddha.”
“What do you mean by that?”
Manjushri replied, “A person who has perceived the uncreated nature of reality and entered into correct understanding cannot again set his mind on attaining anuttara-samyak-sambodhi. The lotus does not grow on high ground; the lotus grows in the mud and mire of a damp low-lying place. In the same way, the Buddha Law can never grow in a person who has perceived the uncreated nature of reality and entered into correct understanding. It is only when living beings are in the midst of the mire of earthly desires that they turn to the Buddha Law.
“If you plant seeds in the sky, they will never grow. Only when you plant them in well-manured soil can they sprout and flourish. In the same way, the Buddha Law will never grow in a person who has perceived the uncreated nature of reality and entered into correct understanding. But one who entertains ego-istic views as huge as Mount Sumeru can still set his mind on the attainment of anuttara-samyak-sambodhi. From this you should understand that all the various earthly desires are the seeds of the Tathagata. If you do not descend into the vast ocean, you can never acquire a priceless pearL In the same way, if you do not enter the great sea of earthly desires, you can never acquire the treasure of perfect wisdom.”
At that time Mahakashyapa sighed and said, “Excellent, excellent, Manjushri! These words are aptly spoken. It is indeed just as you say. Those who are troubled by the passions are the seeds of the Thus Come One.
