It is wrong to force someone to follow any type custom religion or maryada. But the problem is that everyone thinks that his way is only right way. What ever we have been doing becomes only right way and we fail to respect what others are doing or thinking. This is problem with all religions/sects in the world.
As a sikh "Guru granth sahib" should be our only living guru and reference for anything. We should approach other religions/sect/rituals with open mind and then see if it contradict with what our guru says. Religious person should be a student for life and willing to amend as per guru granth sahib. At same time don't worry about what others are saying or following so long as they are not hurting or misinterpreting your religion/beliefs.

same way you can search which jaap should be done as per guru granth sahib .
At last one should be firm in his/her belief and ask help from any of 10 gurus or Guru granth sahib and he will take care of you.
