How does Vegeta become a Super Saiyan Blue?


Vegeta becomes a Super Saiyan God Super Saiyan ( _Super Saiyan Blue_ ) in the
movie Resurrection F. How did he become a Super Saiyan God?

Was the ritual performed on him before the Resurrection F event or did he use
his own power to become a God? (That's what he tells on one of the Dragon Ball
Super episodes)




After reading over the [Wikia
article](http://dragonball.wikia.com/wiki/Vegeta) on Vegeta, it seems there is
not a clear answer on how he gained his Super Saiyan God form.

Since _Dragon Ball Super_ is canon, if in the episode Vegeta said that he
obtained the form on his own I would assume that he is not lying about it.

In the Wiki, it is said that Vegeta went and trained with Whis for six months
before Goku came to join him. It is most likely it was during this time that
he obtained the Super Saiyan God form.

The [Wikia
page](http://dragonball.wikia.com/wiki/Super_Saiyan_God_Super_Saiyan) states
that:

> Super Saiyan God Super Saiyan, also known as Super Saiyan Blue, is the
> result of a Saiyan transforming into a Super Saiyan **after absorbing and
> retaining the power of Super Saiyan God and training.**

That is, that to achieve SSGSS, one must achieve and master SSG first.

However, as it wasn't done before Vegeta went off to train under Whis, the
only options left are that either he performed the ritual on that planet, or
his training with Whis helped him do so. The SSG form is just another Saiyan
transformation, the only thing being different is that instead of normal Ki,
there is divine Ki flowing through your body and you can even perceive it now.
As a result, you can even absorb energy attacks. As Vegeta said that he
mastered the SSG form, I would believe it and would further add that by
mastering the form he said that he mastered the perception and usage of the
divine Ki, thus making it flow through his body evenly and unlocking the SSGSS
form.

There is reference to this in the anime when he senses the return of Whis
([watch here](https://youtu.be/rM19sHdnvQU?t=3m7s)), and later the oracle fish
comments that he's finally able to sense divine Ki. Goku even states that
Vegeta's Ki had changed a lot during the six months he had spent training
under Whis ([watch here](https://youtu.be/rM19sHdnvQU?t=4m42s)).

It's similar to that incident when Goku and Gohan had unlocked the Full Power
Super Saiyan transformation after training in the hyperbolic time chamber in
the cell saga. The FPSSJ transformation was the mastering of SSJ1 and making
it the base form, thus reducing the strain on the body and making it easier to
raise power levels. What they managed to do can be thought of controlling the
SSJ1 Ki and making it flow evenly through their bodies, thus mastering the
form.

The training both Goku and Vegeta are undergoing, which deals with raising
power levels, a manifestation of Ki, without letting it leak, or, in other
words, letting the opponent know, making each part of the body capable of
independent action and also the perception and mastery of divine Ki, thus
mastering SSG, SBG (Saiyan Beyond God) and SSB transformation.
