From Teba Tadahin. About the idea that “Buddha is a man.”

Even if it's written in the sutras, it doesn't mean you should take everything in between. We should break away from discriminatory content.
This kind of story can also be seen in the south, so it's not an original Lotus Sutra. However, on the other hand, according to the sutra of the nun and Buddha called “Terry Garter,” women also quickly became enlightened and received bodhisattva.
Buddhism has eighty-four thousand Dharma. Contradictory content is also included...

It's the Soto sect, but Dogen Zenji also recommends the Hokke Sutra. However, as for women, “Humans are, after all, a collection of earth, water, fire, and wind. Are there men and women?” It explains equality. You probably thought it wasn't a good idea to take everything in between.
It's absolutely useless to use that as an excuse to patchwork for your own convenience, but you should probably get rid of discriminatory statements.

※If you think about it in the direction of daring to defend it, you can imagine that this might have happened if they did their best to explain the salvation of women to the extent that is acceptable in a society where discrimination against women is severe.
However, in my modern sense, it is discrimination. I'm not talking about when the sutras were established; it's a matter of my faith in Japan, and I'm breaking it down as a discriminatory idea.

I see, I learned a lot when I saw Master Sanuki's answers.
There is a passage in chapter 4 of the Book of the Prophecy which says, “Even if you are a seven-year-old girl, she will become a mentor to all people if she causes other bodhisattvas ahead of her own accord.” This is why Metamorphosis Boys have received the Lotus Sutra, isn't it?
In this case, altruism comes first, so it's not when you get the orb (Buddhism), but “in fact, the attainment of the dragon woman's attainment of Buddha was established when an orb was offered to the Buddha,” but rather, the orb (symbol of wisdom) is Bodhicitta... When I first started, I was also receiving a sense of convenience. I see, it's interesting.

On the other hand, there are countries and regions in the south that do not recognize the Hikkuni system established by the Buddha. In other words, women have accumulated merit in this life, and they cannot obtain Bodhi until they become men in the next life. So while men wear yellow clothes, women wear white, and men receive 200 or more commandments for monasticism, women can only receive 5-10 commandments for the home. Women are not officially monks, and this is an idea not found in Japan, such as being half a monk.
That argument is Metamorphic Boys, and even in the same anecdote about Metamorphic Boys, there was such a difference between before and after the Mahayana Sutra... I see, it was a learning experience. Thank you very much. Worship

The requirements for attaining enlightenment, that is, the requirements for becoming a Buddha, are the two resources of wisdom and good fortune.

That is, regardless of gender, if you are a person who can successfully practice dual sustenance, attaining Buddhism is possible, and in particular, in the Mujō Yoga Tantra, it is shown that it is possible to attain Buddhism even in the body of a woman.

As a representative example of this, Chittamanitara Buddha was attained as a woman.

Also, in secret tantras, it is shown that it is possible for Princess Ming to become a Buddha immediately while remaining a woman.

I read your question.
The problem part is about the “five barriers (touch),” and this is part of the reason why women shown by Sharihotsu when saying “dragon maiden can attain Buddhism” cannot attain Buddhism.
It may be interpreted in the Nichiren sect, but in sutras before the Lotus Sutra, it was thought that women could not attain Buddhism, and the “five barriers” come up as the reason for this. This represents discriminatory common sense up until then.
Next, Dragon Girl offers a precious jewel that can be exchanged for everything in the world to Buddha, and next, Dragon Girl's friend transforms into boys and represents attaining Buddhism in the blink of an eye.
This is where the next problem comes up. It's about changing into a “metamorphic boy” man to express attainment of Buddhism.
If you read it as it is, it is quite discriminatory in modern times, but we must consider at what stage the attainment of Buddhism was established.
Actually, I think the attainment of Buddha by Dragon Lady was established when an orb was offered to the Buddha.
This is because I can't think of anything other than enlightenment as a jewel that can change everything in the world. The Buddha received the orb right away.
Seen through the eyes of the Buddha, the attainment of Buddha by dragon maiden has been established at this point, but since no one other than the Buddha can understand it, the dragon daughter can understand it no matter who sees it, so it was shown that even an 8-year-old young girl who is a “metamorphic man” can attain Buddhism with the “Lotus Sutra.”
Therefore, since ancient times, the Lotus Sutra has been worshipped by women as a sutra of “women attaining Buddhism.”
It is definitely not discrimination; rather, it is a sutra where the kindness of women stands out.
The Lotus Sutra is a difficult and difficult sutra, so don't just read the surface of the sentence, but try touching the Buddha's heart behind it.

My interpretation is...
Monjushri brought the dragon maidens to enlightenment.
However, Sariputta told Ryujo, “There is no precedent for women to rank five.” I said that.
In response to this, Ryujo (to let Sarifuta know that the appearance of a man or woman is not an obstacle to reaching enlightenment), changed her appearance to a man in an instant and showed her appearance.
In other words...
You mean that it doesn't matter whether a man or a woman can attain Buddhism.
