Dear Emon,
A very warm welcome to the forums!
And basically the teaching was that you can't always be happy. The way I remember the teaching was that bad things are bound to happen in life.
I was wondering is this true. Or can you be happy all the time? Can the good times last?
I believe what you state above is very wise, and how things are supposed to be on the Earth, to enable our spiritual evolution.
Actually, what makes events seem good or bad, is our own perception on them. Depending on our mood and expectations, one event is some times perceived as bad, while other times it can be indifferent to us, or even good.
We are here to evolve spiritually by experience, and only these events you talk about and we all face, constitute what we call "experience". If we were happy all the time, we would not have occasions to reflect, change our consciousness and grow.
The more "not awakened" a person is, the more they face challenges, to compell them to awake.
The more 'God realized' a person is, the less they 'need' to encounter 'bad' experiences.
So, I believe we meet such events during our whole life. As we evolve, we learn to not see them as 'bad' anymore, but know that we are mighty, divine Beings, and nothing in the world can hurt us, except for our own thaughts and beliefs.
We are here to express freedom, abundance, Unconditional Love.
'Bad' events occur in the areas of our life where we manifest attachments. They are meant to give us opportunities to let go of those attachments, and realize that all we ever could need is only Within.
As long as we don't realize this, such similar events keep occuring in our lives.
I liked very much Julia's sharing, which is indeed the way to gaining freedom and not be affected by what happens around:
When I began to become more aware of my authentic nature and still am, it never stops expanding

, I realized that when I focus on my own life I am able to extend the same trust for another that I have within myself and can allow others to do so as well for themselves.
It is in knowing yourself by being in the joy of the moment yourself expressing in your rightful place in the Divine Plan of Universal Divisity and allowing this to be so for all others.
Also, what Julia shared in the article "
Let Go and Grow Happy!":
"
You are always right where you need to be to take the next step beyond yourself."
We always meet in life exactly what we need, which allow us to further grow beyond our present level.
The only way to live more happiness and less sadness, till the happiness becomes everlasting, is to discover and strenghten your relationship with your Higher Self, the only one which can make you Whole.
Learn to listen to your Inner Voice, to follow your intuition, to 'live in the flow' permanently or most part of your life.
Thus, you can be sure that whatever you experience, is leading to your Highest Good, serves your spiritual evolution. If you feel sadness, it allows you to change consciousness and grow.
My opinion is that all young humans who chose to live on earth at these crucial times are very evolved Beings, here to accomplish their own evolution, as well as for assisting rest of humanity to make the transition.
Therefore, you are certainly more than prepared to face successfuly all that you meet, and fulfil your purpose.
Whatever comes your way, know for sure it is Divine Order, and give thanks for the opportunity to grow.
With Lots of Love and Blessings,
Leila
