How to become restless for God?

Sri Swami Vishwananda:

So, how to yearn for God?
How to become restless for God?
It’s by continuously begging to Him.
To continuously harass Him, by calling His name continuously.
It’s like... you see, human have been born in this world, as if God has given a game, a toy to a child.
The child plays with the toy, but after some time, the child will long for...? The mother!
And when a child yearns for the mother- try as best as you want, give another toy to the child to calm the child- the child will scream! The child will cry!
The more you try to divert the mind of the child, the more the child will scream and call to the mother.
Until the child has not found the mother, the child will not be attracted.
But such crying, if you develop such a restlessness for God, you will have Him.
You will realize Him.
