Yes, as you by keeping on doing japa (chanting) you come to a state of ajapa (practice of japa without the mental effort normally needed to repeat the mantra), you become calm and go beyond the chant, and beyond the name into a state of Samadhi. This is called Bhaava Samadhi.
Bhaav Samadhi is a part, an aspect that should also be practiced. But without knowledge, bhakti (devotion) does not mature. Knowledge and devotion should go together.
