Dear i,
It is best one continues with ones Swadharma and the traditions of prayers that one has been doing. Whether it is loudly, with all pomp and festivities, it is all ok. no need to change anything, it is best to continue as it is, we need not change anything externally, only the inner Bhava needs to be inculcated, and, externally, one need not bring in any change to ones swadharma.
All that is required from our part is SINCERITY alone. The rest, will follow accordingly, the progression of the internalization etc would happen of its own accord.
One may continue to chant mantras prayers loudly, but his mind would be deeply immersed from within.
The outer paraphernalia is less important. One may continue with all the pomp and festivities, but if one is sincere, his mind would still dwell deep within.
One need not change anything.
Stick to Swadharma, inculcate Bhava, and utter sincerity. No need to worry about whether we are doing it loudly, or inner meditation.
