Sr i Ramanuja Munaye Namaha,
Sri Velukkudi Krishnan Swami Guruvae Namaha,
Further reference from Enpani 951, chapter 12 Bhagavat Gita slokam about Mind and Bhuddhi. Though Athma is surrendered during Prapatti by a prapannan, Mind and Bhuddhi also needs to be surrendered on HIS lotus feet to make HIM as our controller.
“Mind thinks BhagavAn Gunas. At the same time, Mind also propells Doubhts. So the Bhuddhi (nothing but Dharma Bhoota Gyanam of Athma) is needed to control the Mind, so both Mind and Bhuddhi are channalized towards BhagavAn SriKrishna”.
Mind: A tool to THINK.
Bhuddhi: A tool to DECIDE.
Mind thinks Perumal is great personality and has great gunas. He is Brahmam (Huge, cannot be seen). Also Brahmam can be seen in Archai deity forms. At the same time Mind also starts analysing like, If Perumal is huge and cannot be seen, then how come He can be seen in deity forms and similar other scenarios and we keep fluctuating.
This means, Mind is enjoying Perumal’s Kalyana gunas, but Bhuddhi is not yet surrendered on HIS feet, which is needed to control the Mind to have a channaluzed thinking about BhagavAn with no doubhts.
So SriKrishna says,
“மனதை என்னிடத்தில் வைப்பாய்,
புதிதியை என்னிடத்தில் செலுத்துவாய்,
இதை செய்தாய் ஆனால் என்னிடத்தில் வசிப்பாய்,
இதில் எந்த சந்தேகமும் இல்லை”.
One who has attained this state (Mind and Bhuddhi on HIS lotus feet) after prapatti Athma samarpanam (prapannan), for those, yes we can say Bhagavan is our controller, like Great Ramanujacharya, Asmadh Acharyas, Sri Velukkudi Swami etc…
For those who have not surrendered the Bhuddhi, then the doubhts propelled by Mind is not controlled by Bhuddhi, and we are the controller of mind, though we (prapannan) have surrendered Athma, like great Agyanis like adiyen etc….But, the solution for such Agyanis is to surrender the Bhuddhi also to Acharyan Lotus feet instead if SrKrishna’s lotus feet, then Acharyan is the controller of our Mind. This is called “Thadutthu Aatkollum Thanmai ” which Swami Ramanujar exhibits to HIS devotees.
