In the Bhagavad-gītā (4.11) the Lord says that how He treats His devotee depends on the devotee's degree of surrender. The Lord reserves the right not to reveal Himself to anyone and everyone but to show Himself only to those souls who surrender unto Him. Thus for the surrendered soul He is always within reach, whereas for the unsurrendered soul He is far, far away and cannot be approached.
