Vajrasatva Practice as training in ultimate Bodhicitta?

I am doing Vajrasatva purification practice, and wonder whether this is a training in Ultimate Bodhicitta? As stated in the Scriptures related to Mind Training: one should first train in Ultimate Bodhicitta. So is purification through Vajrasatva Practice the kind of training to be used to get accustomed to the view of emptiness? Also, is it the best antidote for attachment? Many thanks!
