I asked several questions related to namajapa on our site. Some of them with short answers are given below
Can Rama Nama Japa give moksha? Yes
Is any god name eligible for nama japa? Yes
Is there any relation between (nama) Japa and breath? Seems True
Is 'nama japa without bhava' automatically converts into 'namajapa with bhava'? Yes
When one goes through those questions and answers, it is easy to learn that namajapa is a simple path to get all the benefits that can be achieved by complex sadhanas.
But if we check the other paths like
Yoga, there are several books such as Patanjali yoga sutras, Hatha yoga pradipika, etc.,
Vedanta, There are several books like Tripura rahasya, yoga Vashishtha, etc.,
All the books mentioned in the above two points are available in Telugu also. These books explicitly give the details of the stages that a sadhaka goes through from the starting point to till attaining Moksha.
I want to read the same for namajapa. But when I try to search for those books, almost all of them were not available in Telugu. So I want to find a Telugu book that encompasses all the details from the starting point to attaining higher States.
Is there any Telugu book that is explicitly dedicated to namajapa and covers all the stages of the sadhaka who is doing namajapa?
