Being cheerful doesn’t mean that there is not any unhappy feelings and there’s only happy feelings all the time.
There’s nothing wrong with happy and unhappy feelings. It’s part of the normal function of the mind to react upon coming in contact with the objects of the senses that the mind likes and dislikes, agrees and disagrees with. Or, due to mood swing caused by hormones imbalanced. But cheerful people know that all these feelings are impermanent. They do not have clinging or craving towards happy feelings, or aversion towards unhappy feelings. When happy feelings are absent, they are still cheerful as they are. When unhappy feelings arise in the mind, they are still cheerful as they are.
Those who know non-attachment towards happy and unhappy feelings, they are not being determined by all these fleeting happy and unhappy feelings to be who they are, to be happy or not, to be confident or not, and to feel meaningful or not.
Cheerful people might have unhappy feelings when their minds come in contact with the objects of name and form that the mind dislikes and disagrees with, or when they are not getting the names and forms that the mind likes and wants. Or, when their hormones are imbalanced. But, they know how to let go of unhappy feelings more easily and quicker than those who have attachment towards all the perception of names and forms to be determining them to be who they are, to be happy or not, to be confident or not, and to feel meaningful or not.
The lesser and weaker attachment towards any names and forms, there will be less reasons or lower chances to be unhappy, and vice versa.
Those who have less demand and less expectation, who are less fussy and easily content, who are patient, tolerant, generous, forgiving, adaptable, adjustable and accommodating will have less trigger of unhappy feelings, and vice versa.
Go beyond the identification of ‘happy being’ and ‘unhappy being’.
Keep practicing non-attachment without expectation until the mind is completely be free from any impurities that derived from ceaseless reactions towards objects of name and form influenced by the desires of craving and aversion.
We will realize unconditional peace that is beyond all kinds of happy feelings, and undetermined by any qualities of name and form, when we are free from the desire of want to feel happy and want to be a ‘happy being’, or don’t want to feel unhappy and don’t want to be an ‘unhappy being’. But, allow all the happy and unhappy feelings to come and go without generate attachment or identification, without craving or aversion.
Love ourselves as we are even though the mind is not being happy all the time.
