Although all sacrifices are purifying, one should not expect any result by such performances. In other words, all sacrifices which are meant for material advancement in life should be given up, but sacrifices that purify one's existence and elevate one to the spiritual plane should not be stopped.

That is the highest criterion of religion. A devotee of the Lord should accept any kind of work, sacrifice, or charity which will help him in the discharge of devotional service to the Lord
