Your statement says a very deep thing – “You will walk carefully towards the tomb only when duality is free.” Let us understand it in a little detail:
What is duality?
Duality means contradictory thoughts, feelings and mental confusion. Such as-happiness, sorrow, love-lower, victory-defeat, hope-despair. When our mind is surrounded by these duals, then it stays away from peace and stability.
Importance of meditation and samadhi
Meditation is the process that distinguishes us from the crowd of our mind. When the mind becomes pure and stable, only then we are able to reach the deep state i.e. samadhi. Samadhi is the state where everything becomes united, the mind is in full emptiness and ultimate peace.
How is duality possible?
Being a duality means freeing your mind from all kinds of duality or anti -emotions. For this:
Observe yourself: Whenever the duality comes, identify it, analyze it and separate yourself from it.
Always be concentrated: Learn to focus the mind at one point.
Accept and leave: Learn to accept things that are out of control.
Adopt positive thinking: Practice changing negative duality with positivity.
conclusion
Meditation will be successful only and will pave the way for samadhi, when the mind is duality free and pure. Without duality, there cannot be stability in the mind and it is not possible to have a state of intensive meditation without stability.
Hence it has been said – “Carefully, we will walk towards samadhi only when there is duality free.” It is a guiding theory that suggests that spiritual progress is not possible without inner peace and stability.
