Nectar of Devotion, Tape 3, by His Divine Grace Srila A.C. Bhaktivedanta Swami Prabhupada.

Krsna's another name is Adhoksaja, "beyond the reaches of senses." Anubhava. We can perceive Krsna's there, but not that by our senses. We can touch, we can see, we can smell. That we shall do as we increase, as we purify our senses. Sevonmukhe hi jihvadau [Brs. 1.2.234]. Not immediately.
Just like Sanatana Gosvami. He was talking with his Deity. So as we make advancement in spiritual consciousness, Krsna will talk with us directly. The Deity will talk with you. There are many instances. In Vrndavana, there was Gopala, Saksi-Gopala. He has now gone to Orissa. He talked with His devotees, and went with His devotee.
So Krsna is giving us chance to touch Him, to see Him, to smell Him, to taste Him. By so many ways. This is called arcana-marga. And gradually, when we advance, it will be directly. Just like we are directly talking. That will be possible. So patiently, by following the regulative principles... Sadhu-marganugamanam. adau gurvasrayam. In the beginning, one has to accept the bona fide spiritual master. Sad-dharma-prcchat. Then inquiry from spiritual master. Athato brahma jijïasa. Jivasya tattva-jijïasa. In this way... Tad viddhi pranipatena pariprasnena sevaya [Bg. 4.34]. Pariprasna. In this way, we shall have to make advancement and gradually our dormant love of Krsna will be fully manifest. This is the way.
