In Buddhism an arhat (in Sanskrit), arahant (in Pali) or luohan (in Chinese) means the person who is moving towards perfection or the person who has achieved enlightenment or nirvana. It is a powerful spiritual science that allows a person to spiritually evolve in the shortest time possible.
In the Arhatic yoga there are many purification techniques which helps a person to safely awaken the kundalini energy. What many of us don’t realize that without the purification process any spiritual practices you do would not be safe because within the chakras and aura the ancient seeds and blockages will sprout due to the energy and all these symptoms will magnified. So in Arhatic yoga the first critical part is the purification process.
In the early paintings the Buddha is sometimes also called an Arhat. Both an Arhat and a Buddha were considered to be perfectly enlightened and purified of all defilements. But there is a huge difference between both of them that Buddha is enlightened and an Arhat is considered as an evolving being. Buddha realized enlightenment of his own while an Arhat was guided to enlightenment by a teacher.
In the early school of Buddhism proposed that an arhat might retain some imperfections and lack of purification is also left, so the Buddha is the master of all the masters, the world teacher, the one who opened the door for all other beings.
In the Buddhist system there is a hierarchy to reach towards becoming Buddha is:-
Baby Arhat –> Arhat –> Senior Arhat –> Holy Master –> Chohan –> Bodhisattva’s –> Buddha.
This is a spiritual development phase by which every Arhat practitioner goes through. Although, it looks very easy but this spiritual development takes even incarnations to incarnations. So, “the deeper the purification is, the higher we go”. And spiritual technoz always tell that “in this impermanent world our spiritual development is always permanent”.
