Hare krishna devotees. All glories to Srila Prabhupada and all the devotees of the Lord.
I had a question that i have been ignorant to ask for a while. I am now putting it here. Please solve my doubt.
Dear Devotees i am currently a B.Tech CSE undegraduate student in my 2nd year. Due to absence of exposure of the pure devotees of the Lord i had been an ignorant and materialistic person throughout my life until....By the grace of His Divine Grace Srila Prabhupada my sister bought home Bhagwat gita as it is and that too because she got it from a friend of her's who gave it to my sister for just RS 10 as she already had some other copy of Bhagwat gita at her home. So that's how i came to know that a thing like ISKCON exists. I have been following the principles taught by Gaudiya Viashnav Acarayas for past two years. I follow four regulative principles. Wake up at 3:45 A.M and Chant 16 rounds of Hare Krishna Mahamantra attentively siiting in trance on Tulsi Mala (I was already chanting for one year before i came to know that uninitiated devotees chant on Neem mala so i continued) after observing online mangala Aarti. Initially 16 rounds felt self satisfying but by the grace of the Lord my taste in Naam developed a little and i was unsatisfied with just 16 rounds. Now as i told you that i am B.Tech student, i had to attend classes from 9 A.M-5 P.M which leaves me very exhaustive such that i find myself unable to sit into trance and do Japa. However i invented a solution which was that i buyed a Hand tally counter which is basically a simplistic device that keeps the count of Japa(To avoid any offense to Tulsi Mala) to chant throughout whole day whether it be attending classes or sitting idle.
Now the thing is that the Japa i do on Hand Tally counter is not very attentive(almost negligible sometimes) such that i utter the Mahamantra but doesn't listen attentively due to me being engaged in classes and other activities and by this i am able to do even 100-120 rounds per day. Is this type of chanting offensive....like chant attentively whenever you want otherwise do not because the the name of the Lord is identical to him so when you utter his name he is present and you have to recieve him by the agency of your ears and if you are not hearing the mantra you are disregarding the Lord although you don't mean to. So my question is that whether i can continue doing this routine of 16 rounds attentive japa on tulsi mala and rest rounds on Hand tally counter non attentively. Is there any harm in doing this?
