How shall I know You, O Yogin, by constantly thinking about You? In what all forms of manifestation, O Lord, are You to be contemplated upon by me?
Self-knowledge has two aspects. One is as the sentience, the inmost presence, in the body. The other is as the presence embodying endless forms in the external infinite universe. Having heard Krishna, Arjuna wants to have the spiritual touch even when connected to the externals.
In other words, he wants to acquire full knowledge of the subjective and objective expressions of the Supreme. Mind, intelligence and ego hold the subjective splendour. The objective grandeur is widespread, heterogeneous and infinite, as the world illustrates. In it, what are the special features, excellences, on which Arjuna should contemplate? While living and moving in the world, one interacts with various entities. What, in particular, of these will give a touch of the Supreme? To feel the touch of all is the goal! With that in view, what should receive special or additional attention, enquires Arjuna.
