The merging of the mind and breath is ‘ Dhyana ‘ ( Mediation) and it leads to the natural state when it becomes deep and firm.—–Maharishi Ramana.
Comments; I have been doing this practice for 35 years. I mostly gave an example of Maharishi Ramana because he was a great saint of this age. And my Guru, Saint Nikka Singh ji also advised same things. Truth is one and every saint who has realized the self gives same ideas. There should be difference of words, language, but teaching is the same. But it is not a matter of study of so many holy books. It is a matter of experience of bliss.
As saints define it, they said that mind and breath come from the same source of life. What is Dhyana? When from practice mind emerge in the self it is called dhyana or meditation. And when Dhyana becomes deep and firm it leads to the natural state.
Our natural state is bliss and we want to go there. this is not our real state that is why we never satisfy. we want to go there. As a wave of an ocean twisted and when it emerges in an ocean it becomes one with it, same thing when our mind emerges in the self, then it is satisfying. It is not to find a new thing, but only self – realization. Which already you are! And when mind wandering outside it takes misery. Our saints gave an example of deep sleep, in deep sleep our mind rest in the self and it enjoys there. But there is darkness of illusion. But in Samadhi mind also emerge in the self, but it knows in awakening. There is not the darkness of illusion. Another person can explain it, but you have to understand from your own experience.
