There are four stages of mental stillness as per an awakened meditator mentioned in his book [0]. As per my understanding, you seem to be at stage 3 which is a great achievement.

> On your journey so far, you’ve come off the freeway and you have driven through a suburban road. Now, you’ve hit the countryside road, the third stage of mental stillness. Just like effusive rivers rush into the sea but the sea remains unmoved, the mind of a yogi remains unaffected by the rise and fall of thoughts and emotions. Sea is not always calm, it has tides and it can get tempestuous, but such choppiness is not an everyday affair. A meditator in the third stage can have rough periods but they are far and few in between. From my experience, less than half a percent of meditators get to the third stage of mental stillness. This is not because they are not earnest about it but because wrong meditation does not lead to improvement. When a meditator has gone past the first two stages, they develop an unfailing stillness of mind that reflects through their actions, thoughts and speech. The energy of a stage three meditator has a quieting effect on those around him. The third stage is the countryside road. You can drive for several miles before you come across any other vehicle. Green fields, meadows, pastures, pristine air, blue sky, expansive views, beautiful landscapes, quiet surroundings, no rush – ah, the pleasure of countryside driving! You can go slower or a bit faster, you choose your own pace. The conditions permit you to do that. A meditator who has reached stage three learns to harness and channelize his thoughts. Most of their sessions comprise spans of quiescence and bliss with occasional thoughts emerging here and there, on and off. They don’t get up all relaxed from their meditation, for relaxed they already are, otherwise it would not have been possible to get to this stage. Instead, they get up feeling supercharged, refreshed and alert. A great meditator is always alert. Alertness is not only the reward but an essential ingredient for good meditation. A stage three meditator can easily sit unmoving for three hours.

I'd recommend you also read on Kundalini [1]. You have a great chance of awakening it in short time and experience the supreme level of bliss and peace.

Also, I request – it'd be great if you can join https://os.me/ and share your practice/experience as posts with spiritually inclined seekers out there.
