Sree Sree Guru Gaurangau Jayatah!
A sincere disciple should see his gurudev as the Grace Incarnate Form of the Supreme Lord Sri Krishna. You should know that the relationship between the bona fide guru and the bona fide disciple is eternal. There cannot be any severance of such eternal spiritual relationship. Although you may not see him physically by your material eyes, the Absolute Counterpart of the Supreme Lord, gurudev, is as eternal as the Supreme Lord. Gurudev is the Grace Incarnate Form of the Supreme Lord Sri Krishna. His grace is upon you, always. You submit your prayer to your gurudev wholeheartedly and worship your gurudev, which every disciple should do always. The worshipper should first worship guru and after that, taking his permission, can worship Gauranga and Radha-Krishna. The Supreme Lord and His personal associates do not give importance to words but they see the heart of the worshipper.
