Giving allows others to receive. Receiving allows others to give. It is a circle, a cycle, a continuum.
It simply means that if you wish for something, and instead of expecting the receiving end, be the GIVER. Let go unpleasant emotions such as selfish, anger, annoyance, sadness, reckless & childish and somewhat erratic behaviour etc. etc.
If you want to be happy, do not seek for it. For happiness comes within. Seek inner peace. Forgive yourself, forgive others without any condition & resentment and seek spiritual rejuvenation for your soul. When the soul is truly happy and full of joy, even the most deadly disease will cease to exist. It is that simple.
When you give, give your all in good faith without any expectation, for the Universe will repay you. It is all about the energy.
You can choose to break the circle or to keep the energy flowing.
Instead of seeking others for comfort, meaningful relationship, conversation etc. etc., be humble and do the opposite. Give your time to people, to friends and do it with good faith though.
Get out of your comfort zone whether you are introvert, semi-introvert, extrovert, extreme-extrovert...Stop the sour-face, sad-face, long-face, face-in-pain and subtle & deadly resentment. Start giving your time to others even when adversity is hammering on your face.
Ask yourself, when was the last time you actually gave a hood about someone who cared about you, your health and well-being or someone who just made your day when needed most or when you were down, ill, in-pain, in-confusion, in-trouble etc. He or she may not be your best pal but nevertheless kind in nature and were there when needed most.
When one takes the other for granted, the universe does the same. When you take, you must give with complete honesty, compassion, joy, love and good-faith. The other person must feel and believe that you are doing so with such a manner too. You can lie or pretend to a person(s) but not to the universe and your inner-self.
Here's what the Dalai Lama says:-
“As human beings we all want to be happy and free from misery… we have learned that the key to happiness is inner peace. The greatest obstacles to inner peace are disturbing emotions such as anger, attachment, fear and suspicion, while love and compassion and a sense of universal responsibility are the sources of peace and happiness.”
Last but not least have inner peace, happiness, do good, give others your time as well and may the universe & the almighty God pour upon his blessings unto you.
