The concept of Heaven is simple extrapolation of materialistic pursuit graph. A person is always engaged in creating means
to increase pleasure in his or her life. A master simply gives a bargain of a pleasuresome heaven to the Sravakas.
The concept of Heaven is similar to a process a parent adopts to teach lessons to his or her children.
If a child does well in the lesson, some immediate rewards may encourage the child. Visualization and description of
Heaven is simply to lure Sravakas to act in righteous manner in order to get rewards in the afterlife.
All masters including prophet Muhammad have used the same lure to attract beginners to the righteous path. The visualization of nymphs, Hur, wine, gardens, pleasure is hence appropriate and useful.
