Sree Maa Shri Ji explained to us about the Guru Mantra and then gave us time to think if we wanted to be initiated into it. As Dakshina, each one of us gave a bad habit that we wanted to get rid off. Guru Mantra was the doorway to be initiated into being a Sanatana Dharmi, the one who lives righteously like an akarta - akarmi (non-doer). All this was explained very clearly.
i already had 3 mantras that i was using to meditate on, two had been given when i was initiated into TM and the third one for Sahaj Samadhi meditation and all 3 had been substantial in my spiritual growth. i didn't know what to do with them and voiced it to Sree Maa Shri Ji. It took 1 minute for Sree Maa to clear away the antar-dwand (inner conflict) i was experiencing based on one of the discourses Sree Maa had given previously and it made sense that all mantras initiated from AUM. i chose to receive the initiation.
During the initiation, the conflict that i had experienced earlier came and stood right in front of me. My own conscience shouted at me for being selfish and betraying my first Guru Sri Sri Ravi Shankar who had helped me unconditionally in my time of need. He never forced his teachings and courses on me, i had gone and done them, benefitted from them and chose him as my Guru, taken respite at his Ashram and now suddenly as i found something more advanced and better, i was disowning him. i felt really bad that i was letting him go after selfishly using him, his teachings and his techniques until i wanted to. The tap of tears opened again and i just couldn't move forward to receive the soundless sound mantra. At that moment, i called out to him and he showed up. The closure that he gave me has been instrumental in keeping my faith in the Guru principle and to move forward in truly accepting Sree Maa Shri Ji as my Guru. i still find it very overwhelming to express this part and am taking the liberty to share the audio recording where i shared my experience. Humbly requesting all listeners to listen to it from the recesses of your soul and not the judgement of the ego as i was reeling under very intense emotions and a phase of shift and transformation when i did the sharing_/\_ Gratitude in advance for your understanding and empathy_/\_
