Dear All..
Yes Nama Japa is very powerful too.. There is no one single medicine for everybody, like Bhagwan recommended different style for different people based on their maturity.
When it comes to Nama Japa, it should be done by the mind as Bhagwan said. Rather than saying it out, he recomended saying it by mind. One can start with pronouncing with tongue mildly and slowly stop using tongue and produce the sound just in mind.. This takes one deeper.. That goes deep inside slowly. This is really possible. Everyone might have undergone day dreaming or thinking of something else sitting in class room or work place or anywhere else.. When those thoughts or scenes in mind can be brought easily without opening mouth or moving tongue, why not a small syllable. It really comes for an earnest seeker who is willing to give up anything and everything for the Atma Jnana.
As one takes the nama japa deeper and deeper, it dissolves at the very bottom. And, another short cut here Bhagwan says is - at some point of time find out who or what is that uttering the word or mantra without the help of tongue or mouth, there one can try to differentiate the ego and conscious.. holding to that should be fine I believe.
Anyways, when we want something that is not working out, keep praying for it from Bhagwan every now and then.. HE is ready it give it immediately.
With Love
