Internal and external has many translations in the Martial Arts,

You cannot be one or the other,

Because we all have an inside and an outside,

If you are more one than the other, you are unbalanced.

If you’re taught externally,

Your instructor will correct you by how you look on the outside:

If you’re taught internally,

Your instructor will correct you by how you feel inside.

Ideally, you need both.

If you train externally,

You will utilise the power of emotion,

If you train internally,

Your mind will be calm and focused.

If you train externally,

You will use the outer muscles in small combinations,

If you train internally,

You will use the deep muscles and spine,

All connected and moving in harmony.

The deep muscles and spine hold emotion.

They also support the internal organs.

Softening and correcting them,

Will increase health and vitality.

Many martial arts go from more external to internal.

Some from more internal to external.

It’s always good to train both in balance.

Because you can’t have just an inside or outside.

When you move one you always move the other.
