When we speak of Kṛṣṇa, we mean God. Everyone has some vague idea of God, but no clear idea. Therefore God descends to show what He is. If we speculate on God, someone will think one thing and another person will think another. This is the result of speculation. But if God Himself comes and shows Himself as He is and speaks about Himself, that is perfect knowledge.
This Kṛṣṇa consciousness movement is spreading that message. God Himself is speaking about Himself: "I am like this, I am like this. My form is like this. My activities are like this. My address is this and that. If you like, you can come back to Me. This is the situation. Everyone can come to Me." All this information is there in Bhagavad-gītā As It Is. In Bhagavad-gītā God speaks about Himself and presents Himself as He is. We have simply to take that information; then we can understand God. As soon as we understand God, we can go home immediately. It is a very simple thing. God says:
- janma karma ca me divyam
- evaṁ yo vetti tattvataḥ
- tyaktvā dehaṁ punar janma
- naiti mām eti so 'rjuna
- (BG 4.9)
"One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna." So God is there, that's a fact. Anyone can go back to Him and live an eternal life full of bliss and knowledge simply by knowing about it. When God Himself comes, all great ācāryas, stalwart men, accept Him: "Yes, He is God." If we simply understand God, we make a solution to all our problems. What is the problem? Because we are part and parcel of God, we are qualitatively equal with Him. God is eternal, and we are eternal. God is blissful, and we are blissful. God is full of knowledge, we are also full of knowledge.
Unfortunately, we are hampered by this material body. Therefore our problem is how to get out of this material body and come to our spiritual body. The spiritual body is there, just as our real body is present underneath our shirt and coat. I, you, and every one of us is a spiritual spark, part and parcel of God, and we are placed within a gross and subtle body. When this particular body is finished, we are carried by a subtle body into another gross body. That is called transmigration of the soul. And when we finally get free from the subtle body also, we go back home, back to Godhead. It is that easy.
