Here is simple line from Ramana Maharshi
The second line – ability to focus within to a single entity ( Maharshi uses the word to a single thought)
Well first one has to find something within where you can focus your attention ( requires a Guru ) –
Then hold to it steadfast
Finally one has to Merge in it. ( conquering ego )
These three steps – when done simultaneously is sayam. And when done – is savikalpa Samadhi
The next step ability to keep unwanted thoughts out is much harder. On a gross level it requires faith God will take care of me. But it is much more. It shows transformation of the mind! What does it transform to?
Good question isn’t it?
This is nirvikalpa Samadhi. This is the final step when done while doing all activities
This is a very high quality meditation. Almost all who read it should use this as a gauge to progress.
Now if you think about it, this is peace isn’t it? Not a single unwanted thought? Aah And what do the fools of the world try to do? Change their life? Instead it is better to change yourself.
Since holding the attention to the single entity – that ultimate entity is God. You can measure your closeness to God.
After all when you have God do you worry at all?
Part 3
Now of course there are many levels and layers on the way. I mean after you can achieve this – they go by many names. Hinduism is the only religion that even after you reach God, there are many more levels.
I only described the beginning – keeping unwanted thoughts out!
If you want to make progtess, first be honest. Realize that you have not made the first step. Don’t have the ego you know something. Just practically try it. Let someone close to you insult you today and see if you can keep unwanted thoughts out!
Once you realize that you can’t keep unwanted thoughts out, then find someone who can teach you how to do it
Until then you will remain trapped for many many births / years / centuries
Sadly there is no other way
