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.'

My Devotees are content with serving Me with Loving Devotion
The ultimate result of singing God's names is unconditional love towards one and all.
The service that God has entrusted upon your shoulders is to lend them to me!
If it is even possible for you to make one other person chant the Mahamantra, that is the greatest service you can do to Him
To have the opportunity to serve a Mahatma in some way is indeed the rarest of the rarest.
So if you keep chanting Mahamantra, actually the Guru reaches you!
Take the Name constantly. That is the best Seva.
But if I can make a person chant the name of Hari, I consider this a bigger achievement............
To collect people living around one's home and help them chant the Lord's Name is verily service to the Guru. Or to follow the special instruction given to him/her by the Guru is verily 'service' to the Guru.
Serve the elders, poor and needy and people in misery. That is verily Guru Seva.
