Cooperation comes when there are pure feelings and good wishes for all involved in the task.
When you are working for something and that task is for common benefit, you will find that others will easily cooperate with you. Also their good wishes help in the success of the task. When you take up something new and important, make sure there is some benefit for everyone involved in the task. When you do this you will find that everyone will cooperate with you.
~ Brahma Kumaris, Mt Abu.
