The difference is subtle. It is the difference between living with God and living near God. Both are the result of bhakti. Near is just a shade further than living with, in the same house. Samipya is that God is always within your reach even though you have your own independent life. Salokya is that your life has become completely intertwined with God. To complete the picture Sayujya is becoming one with God and sadharmya is putting on the same Nature as God’s.
Affectionately,
