Jay Jay Shri Gokulesh,
This topic is very intresting and very vital to get correct answers rather then gussing it.
I read word "BHAV" in most vaishnavs reply. " BHAV" to Shri VRAJ BHAKTO NO HOAI, AAPNE TO TENI BHAVNA KARVANI CHE. We are not capable of to have "BHAV".
Second thing is there is no set of Rules : Which make me to think for moment.
In PUSHTMARG every thing is defined in it's proper terms and definite rules regulation. I remember a STORY for the SEVAK of Shri Chaitnya mahaprabhuji and Shri Vallabha mahaprabhuji.
One of the sevak was reciting Shriji's smaran while he was in toilet and If I am not mistaking then Shri Vallabha Mahaprabhuji is correcting on this situation for not to recite shriji's naam unless you achive the state which "Shri Krishna das" ( Shri Mahaprabhuji's serve shresth sevak did).
Mantra is always recite in away that even the next person should not see your leaps movement.
For other detail queries Shri Chaturt Peethadhiswar Shri Devkinanadan acharayacharan have published a small Granth where Aap Shri have answered most of the questions ( Pure time & impure time)
Also Shri Vittharaiji Prabhucharan aatmaj of Shri Chaturth peethadhiswar have drafted an article for modern word "How to do Satsang". In which Aap shri explains How one shoud handle all SWAROOPATMAK SAMAGRI.
All granth's are NAMATMAK SWAROOP CHE, and all items used for Shri PRABUJI ( SHRI THAKORJI) is SAMAGRI che.. So one have to be carefull about what you do, How you do and when you do.
Best thing is I am requesting Shri VitthalRaiji Prabhucharan to shade some light on this string.
I am sure Shriji will swikarse aapdi vinnanti..
Jay Jay Shri Gokulesh
