The shattering of the sword of the Vriti can be understood in two ways. The first way is the mind will become without Vriti at that time. At that point you realize, I always was this unlimited consciousness. All the Vritis of the mind play about in this ocean of light which I am. That would be Nirvikalpa Samadhi and Advaita Vedanta.
