Our this human form of life is meant for going back to Kṛṣṇa, back to home, back to Godhead. This Kṛṣṇa consciousness movement is giving information to the people in general how to make life successful. What is that successful life? To go back to home, back to Godhead. This is not our home. This material world, this is foreign country. We are... Just like I am travelling all over the world. My home is in India, but I am going to so many countries, Europe, America, Canada, Australia, Africa... But my home is in India. This is a crude example. Similarly, we are all part and parcel of Kṛṣṇa. Mamaivāṁśo jīva-bhūtaḥ [Bg. 15.7]. Kṛṣṇa says. "All these living entities, they are My part and parcel."
