Freedom within

Today I feel very relaxed because I have zero worries for this moment but can it be maintained.
The type of relaxation is so nice. This is freedom within unlike those excitement come from bodily excitement.
Perhaps we have to experience this type of " freedom within ". This is the pity things in life to not experience the emptiness.
Many human beings just know how to fuck, eat. The whole life is just doing some action ob the bed. Again and again and addicted on it as if the whole life just doing that type of acts.  How can they know the feeling of emptiness? How can they have wisdom?
This article is for myself to read and as the reminder for me.
