As per my personal experience to form this opinion:
Ram is coined by an Indian mystic as recitation of ॐ or Omkar word all the day is not possible. Recitation or continuous remembrance or as Buddha called it right mindfulness (Samyak smriti) is a must because it brings a persons attention on himself/herself. As soon as the other comes into mind, the mind starts talking verbally or mentally. If there is no other in your mind then you are living in present or living in kingdom of God or living in RamRajya. The other brings you into this world or a writer called it ‘the other is hell’.
Becoming a Buddha means remaining in 24×7 in this state or living in RamRajya or living in kingdom of God 24×7.
Through recitation of Ram a similar sound generates that creates equal/similar effect on person reciting ॐ. Mystic Nanak and Mystic Kabir called it as ‘Naam’ to clarify it as different from the King Ram. May be after 1000 years of this discovery of word Ram, king Dashrath used it as a name for his eldest son. So there is no connection between Ramrajya or Kingdom of God and King Ram’s rule after he arrived at Ayodhya. Everyone enters as a King of this inner kingdom of God or inner RamRajya and before entering he/she becomes fearless. People were so fascinated by this discovery that they used this word to salute even unknown person.
Now a days some political people in India are trying to bring Ramrajya again in India, which is impossible because even the Earth was never remained empty of such King ie enlightened persons, of the kingdom of God or Ramrajya and continue to be so for eternity. This political Ramrajya is based on fear, instead of fearlessness achieved before entering in inner Ramrajya and except few mischievous people all will be slave instead of everyone enters as a King in inner Ramrajya or Kingdom of God.
This political Ram has no connection with the word Ram coined for chanting of symbol ॐ. The inner Ramrajya is ultimate destiny of everyone.
Why recitation is needed?
Once a person attains 7th rug of the ladder or reached 7th Chakra of body in his/her spiritual journey, it is needed to get dissolved with God/Cosmic-consciousness. Buddha too in his book ‘Heartsutra’ advised Sariputra to remain in Meditativeness ie constant remembrance of emptiness which is same as reciting Ram or ॐ living in Kingdom of God. Once dissolved with the cosmic consciousness or God, then person cannot come back to his/her body form however the body can be used for helping people in their spiritual journey. Even it is necessary to leave body at will because one is already living at centre, just the cloths (body) needed to be removed at that time.
After leaving body they, mystics in invisible form or formlessness, continue to help people in their spiritual journey irrespective of location, country, colour, culture, lineage etc.
So one needs to put in dedicated effort to keep this remembrance that this visible and invisible world is Kingdom of God, and the seeker is performing every act for God’s happiness. With attitude of gratitude that he/she is given this opportunity. The body and all other visible things, people etc are part of a grand drama that is beyond his/her understanding. This way call it Ram Rajya or Kingdom of God, it is same. Osho said that the Sakshi/Witness/Drishta will be one who is able to see both 1) Kingdom of God and 2) Whole visible world including his/her own body at time as a drama played on a grand stage with the person executing his/her role as infinitesimal part of this infinite and eternal play/drama. Through witnessing one can get transformed.
