<p>Yin Release and Yang Release should explain this with sources, alternatively @BeyondRed explained it as well. </p>

I don't quite understand how Yin Release can only consist of spiritual energy... the same with Yang Release.

<p>Reread BeyondRed's response. </p>

<p>It's not entirely consisting of spiritual energy. There's just very little physical energy in Yin Release. And vice versa for Yang Release. </p>

<p>One way of thinking about Yin & Yang Releases is to assume a change in the ratio of its composition of physical and mental energy. Another way is to understand it as just another Nature transformation: Chakra is "disguised as", or takes on the properties of, a natural element: In this case, chakra would take on the characteristics of "spiritual energy" for Inton and "physical energy" for Yoton, including the effects those energies would have on other things, while still remaining Chakra underneath, and thus subject to Shape transformation </p>

As far as I remember, "Naruto Hiden: Rin no Sho" clearly states the equality of energies / ratio, for example 1 to 1... </p>

<p>Yes, it does, but since when does anything ever make sense in <i>Naruto</i>? :D </p><p>I guess you could circumvent it by saying "Normal chakra has a 50/50 ration, special chakra (YinR, YangR) doesn't". </p>

<p>Yeah, it's true. </p><p>But still, from your conclusion / assumption, it turns out that any mediocre shinobi who can't balance (50:50) energy is a Yin Release or Yang Release user. </p>

I think there's still a difference between not being able to balance chakra and purposefully using a ratio other than 50/50. But that's going into speculation anyway.

<p>I don't think it was ever stated anywhere that balancing the two energies is hard. According to Ebisu, the real hard part is creating just the right amount of chakra you need and then converting it into a technique, since any extra chakra is "wasted" (which doesn't really make sense either, honestly). </p><p>Another oddity is that Shikamaru treats Yin Release chakra like it's special and only used for rare techniques like his, but apparently it's part of every common genjutsu. This is probably just an example of Kishimoto not thinking things out in advance though, since he didn't actually mention the term "Yin Release" until years after the Tayuya fight. </p>
