Prof Nara ji,
I was also a Nasthigan at one time( almost 45 years back in the early seventies) I was very much interested in EVR, Abraham Kovoor and others.
Due to family circumstances, I was unable to continue to be Nasthigan and was forced back to the present path.
But in the present path also I always go for validity and proof. But getting validity for everything is difficult and not possible.
However I have not given up my rationalistic approach even today.
Going back to the actual incident which I narrated - rat, rat trap and a masal vada.
Rat was not attracted towards a coconut piece and escaped from the supreme sacrifice. But later when Masal Vada was placed in the trap, it could not resist and paid the ultimate price.
Why this happened.
Purely because of thoughts. May be good thoughts (Noble thoughts which I am subscribing at the bottom), Normal thoughts and Bad thoughts.
From where thoughts originate?
Mind is the general answer which we get.
Where is the mind?
Nobody is able to show it physicallly.
I searched various religious literature but I was not convinced about all like you.
I attended Maharishi Mahesh Yogi's transcedental meditation classes but somehow I was not convinced and gave it up
Almost about two decades back, I came across Paul Brunton's book on Ramana Maharishi
Since it was not involving any specific mantra, religion of God, it somehow appealed to me and I started investigating to Ramana Maharishi's philosophy.
It involved simple repeated self enquiry `who am I?' நான் யார்?
The originator of this thread Sri Arthur has also posted the same question in his first posting.
Ramana says the question drives away thoughts. I personally experienced it, definitely repeated questing of self drives away all the thoughts including good thoughts.
Driving away all the thoughts is a good idea but it came at a wrong time. Twenty years back all my kids were just doing primary schooling and I had lot of commitments to my family. So I gave up further self enquiry at that time and decided to take it up at a later stage (Probably at Vanaprasta time)
Ramana says there are two hearts in our body. The physical heart in our left hand side and the non visible spiritual heart on the right hand side.
It is up to you to believe it or not and I have no issues on that. But my self enquiry experience definitely drove away thoughts and I was able to experience bliss on the right side of my heart.
Probably if I had continued, I would have had the experience of identifying myself with the inner `self' but not with the physical body.
If you are interested please go through the following thread
Self-enquiry (Vicharasangraham) of Bhagavan Sri Ramana Maharshi on the website dedicated to Arunachala and Bhagavan Sri Ramana Maharshi
Again I am telling all that one has to experience it themselves individually and any amount of explanation is not sufficient.
I request others to share their experiences if they have taken similar path.
All the best
