Salokya, Saroopya, Sameepya, Sayujya

Saalokya, Saaroopya, Saameepya and Saayujya is generally explained as —-
When a person worships [does upaasana of] a Deity he attains to the world/plane [loka] of that Deity. This is called ‘Saalokya’.
He then attains ‘Saaroopya’ – i.e. he attains the form of that Deity.
Then, he attains ‘Saameepya’ i.e he attains proximity to that Deity.
Finally, he becomes one with that Deity ‘Saayujya’.
Sri Swamiji explains this in a very wonderful way:
When a person does incessant chanting of a Naama in the same place, divinity is created in that place around him. This is verily ‘Saalokya’ [same loka]. That is he attains to that world/loka, here. He then attains the beauty of that Deity or in the case of the worship of a Guru, his gait, talk and everything else becomes just like that of the Guru – ‘Saaroopya’ [same form]. Then, the Deity comes into his heart, which is verily ‘Saameepya’ [proximity] and finally he becomes one with ‘It’ and that is ‘Saayujya.
These are not really external factors as deemed but happen wherever the Nama is chanted incessantly in one place.’
