How should we meditate upon Krishna as per the Bhagavad Gita?
We have five knowledge acquiring senses plus the mind, and five senses of action, they should all be engaged in connection with Krishna and then naturally our mind will be fixed on Him. See the world as belonging to Krishna, taste Krishna prasadam, hear bhajan, kirtan and Krishna katha, smell incense that is offered to Krishna, touch the deity form of the Lord while bathing and dressing it. The concept that Krishna gives is total absorption while continuing with daily duties and activities. He does discuss solitary meditation, but Arjuna is nonplussed with the idea saying: Bg. 6.33 - Arjuna said: O Madhusudana, the system of yoga which You have summarized appears impractical and unendurable to me, for the mind is restless and unsteady. Krishna agrees that it is hard to do and later He will give alternatives, but the principles of yoga must be kept. Controlling the mind and focusing it on Krishna are non-negotiable, and the highest yogi is the one who serves Krishna with love. Bg. 6.47
