You can remain faultless only when you constantly remain as a nimit [instrument, one of the doer and not the whole and sole doer] and remain in the intent of being an instrument [intent that I am one of the doer of many scientific circumstantial evidences]

Everyone is born with the nimit (karmic evidentiary instruments). I too, am born with nimit. With this body, so and so number of tasks [work] will be done by him, such is the nimit!

In this life, you only need to do this much: You must know that the other person is instrument (nimit, in bringing you the results of your own karmas) so you must remain silent. Do not let the mind spoil in the slightest. If it does, then ask for forgiveness: ‘Dear Instrument! You are simply an instrument. I ask for forgiveness for spoiling my mind.’ You have to do only this much! That is the effort [purusharth]!

Mantras are to be recited together. Mantras are an instrument to please the celestial deities.
