The true criteria for understanding the Lord is attachment to His Lotus Feet, because the Lord will reveal Himself. So one can not satisfy the Lord with the blunt material senses, one can not in any way approach the Lord with just the intellect….but when the Lord is pleased by devotional service performed in attachment to the Lotus Feet of Krishna then He will reveal Himself……
Attachment to the Lotus Feet of Krishna changes our whole perspective in life because as we get attached to the lotus feet of Krishna then we gradually lose our self interest as to: my likes, my dislikes, my desires to somehow or other doing what is important for Krishna, what is really serving His purpose and in this way our life becomes a life of sacrifice for Krishna. That will bring us close to Krishna. Then Krishna will reveal to us how to understand Him. Krishna says: “I will give you the intelligence so that you can come to me” and ultimately that is the process.
