Wise people never pray for specific things, because they know ‘that which is not destined to happen as a result of fructifying karma will not happen.’ Inquiry into Existence’, James Swartz
With this in mind we could teach our children to pray for the chance to make a contribution to the field, for an intellect that can understand who they are, and for gratitude for what they have.
These are all things Ishvara can readily provide, and as they put these thoughts and actions out into the world, the world will respond in kind. They will generate positive karma, which generates more positive actions and so on. The seen and unseen effects of their daily actions will help them to understand the personal benefits of having positivity and the posture of contribution as their primary stance.
