The trouble must be there because God has created this world for your enjoyment and for my enjoyment, there therefore must be struggle. Because I don't agree with you, you don't agree with me. So why there shall not be trouble? Because everyone, if everyone . . . just like in office, if everyone wants to become the proprietor, will not there be confusion and chaos? Do you think the office will go on nicely?
Similarly, here, God has given you chance to become master because you wanted. But everyone wants to be master. There is chaos. How there can be harmony when everyone wants to become God? Do you think it is all right? There must be chaos. Here is the position. Everyone in the material world, first of all, they want to become big man, big businessman, big, big this, big that, minister, president; and when everything is failure, then he wants to become God. That is the last snare of māyā.
So this is going on. How you can expect peace and prosperity here? That is not possible. Duḥkhālayam aśāśvatam (BG 8.15). It is stated by Kṛṣṇa Himself that this is a place only for misery, but under the influence of māyā, we are accepting all miserable conditions of life as happiness. This is called māyā.
