[Realization of spirit and soul]
If you are not developed, you cannot feel happiness.
Development
Even though a person grows up, if they do not develop themselves, their function is weak so they cannot display their value as much as they grow.
Even though a person grows up, if they are not developed, they cannot feel happiness even though they experience happiness.
The brain and the mind must be developed.
When you display your function, you are happy.
Try to improve and develop your brain and mind.
If you keep stimulating your brain in a good way as listening to the Holy Son's word, praying continuously, conversing with the Holy Son, and taking action according to the word, it will be able to function.
A jewel shines its light when it is processed as much as it grows big. Likewise, also a person should make themselves so that they can function as much as they grow.
