Only those who are completely devoted to God, get him. This does not mean that He is difficult to get. On the contrary, he is equally present in all beings and vice versa. He neither likes nor dislikes anybody. However, those who are his devotees He resides in their heart and they reside in his. If you can't forget him then he can't forget you. That is the greatness of devotion to Him. Just like sunlight is reflected by all objects but it is reflected most in the mirror than in any other object. That's not because the sunlight falling on the mirror is any different; it's because of the mirror.
