晴空万里的夏日，如果我们观察一下天空，且背向太阳，极目仰望，就会发现头顶上空的蓝色最纯净，最浓郁。靠近天边，色彩往往较暗淡，太阳周围的地方则略呈黄色。这是因为我们向天边望去时，目光要穿过极厚的低空大气层，其中布满颗粒较大的尘埃，反射出白光，这就冲淡了天际高空大气层的纯蓝色。在太阳附近，大量蓝光则由细微的尘埃反射回太空。这样，主要由低空大气层的粗粒尘埃反射到地面的光线，便带有浅黄色。不过，在日出日落时，由于光线到达地面南非要穿过厚厚的大气层，这种反射效果大大增强了。只有在这种时候，我们才可以直视太阳，即使万里长空没有一点云彩，不见一丝雾霭。这就充分显示了低空尘埃的数量之大。但是太阳的光线终于到达了地面。它们先是穿过厚度极大的高空大气层，其中的细微尘埃把大部分蓝色的光反射掉了，让补色的黄光继续通行。然后，粗粒尘埃又反射掉绿色的光，让偏橙色的光继续通行。
最后，部分黄色的光也反射掉，剩下几乎是纯红色的了。不过，由于不断出现气流，把法埃与水汽分层排列，广度不均，密度各异，加上高低空常有云层，不同程度地吸收并反射阳光，我们这才看到各种奇异的色调斑剥陆离，诸多绚丽的色彩变化万千；任何人只要有幸将西方的景致一览无余，只要有心观看大自然不时展现的那一幅幅瞬息万变的彩画，都会为之赞不绝口，喜不自胜。随着夕阳缓缓西坠，这种景观也不断变幻；尤其是在太阳沉入地平线之后，由于角度更加适宜，五颜六色的光就都发射到地面上来。遇有些许云雾，更是如此。本来，只要太阳还位于地平线之上，云雾便截住了不少夕阳和色彩；而今太阳从我们的视野消失，阳关便更为直接地照射到密度各异的重重云霭与层层大气的底部；一片崭新的、更加灿烂的阳光染红了西天，一幅景观色彩绚丽，变化万千，观赏者固然赏心悦目，然而自叹莫及。而我们之所以能领略如此无与伦比的美景，全应归功于——尘埃！
Eight Effective Ways to Stimulate Your Passions八种激发你激情的有效方法
You were born with a passion to do something unique with your life. As a divine being it was given you from the infinite supply of the universe. As an unborn child in your mother's womb, you had it swirling all around you, and it lived and breathed inside of you, even before your little lungs developed.
It survives by simply being—no thinking required. Passion is a gift from the Universe. It’s in you, even though you may have forgotten what it is and how to access it. The key to uncovering your passion is a process. Take a look at this step-by-step process and then actually practice the steps. Before you know it will be living with passion rather than just dreaming about it.
Spend more time alone
When you surround yourself with lots of people, or even one very strong individual, it is difficult to know what excites you. It is easy to become influenced if outside energies are stronger than yours.
Consider this a time for self-care. Be easy and respectful of yourself. If you choose to hang out at home create a space that is uncluttered and peaceful. If you go outside, make sure it’s an area that you will not be disturbed.
Heighten your awareness
No matter where you choose, look around and learn to really appreciate your surroundings. This is a space you selected, so be aware of all the details that made it your place of choice. Use your senses to take in the beauty, scents, textures, and sounds.
Expect your experiences to be subtle. When you catch the scent of the candle by your bedside, this may invoke a distinct taste in your mouth. Your sixth sense (instinct) will also play an important role. Use it to make your space more appealing with time. Refine your sacred space so that it brings out the best in you.
Reflect
Once you are comfortable in your space, close your eyes. Put your focus on the fact that you are pure energy and, because of that, you are a vibrational being. Let this really sink in.
Allow this reality to make you smile and feel delighted. You are not your body, your mind or your beliefs. The thing that is really you is eternal, creative energy. Everything else is a temporary body with an ego attached.
Write down your revelations.
Once you are able to wrap yourself around the idea of who you are at the core, write these thoughts down. Explore how this makes you feel. If you really "get it" you will be feeling very powerful.
This is a power supported by the universe, not one created from your ego. That means whatever you choose to do you will have the support of the infinite energy of the Universe. Knowing this you will be less likely to hold back about what would make you truly happy.
Write down your passions, no holds barred. You do not want to leave this planet with regrets. You were given life here on earth to express yourself in your own unique way. Everything surrounding you wants you to succeed!
Dig deep and write about what you would love to do. Do your best not to allow worries to crop in. The only stipulation is that your intention is pure. If you have read this far with an open mind, you already have a clear intention.
Experiment with your choices
Okay, it’s time to get out there and have some fun in the real material world. Take a pottery class, attend a lecture on photography, join a writer’s group, go deep-sea fishing, etc, etc. The world is your oyster.
By now your instinct should be gearing up (if you've been practicing the previous steps) to provide you with indispensable guidance. Pretend that divine energy (God, Spirit, Our Inner Source) is in the driver’s seat. Your backseat driver days are over. If you used to be frightened about how you were getting to a certain location before — now, you simply trust that you will be led in the right direction.
If you take a wrong turn (or pick a class you decide you do not like), simply take another road (another class) next time. There are no mistakes-only adventures and experiences. Have fun on this ride.
Bring clarity to your passion
The universe likes specifics. If you are clear in what you want, these things will more likely show up for you. Many people find themselves stuck here. You may find that you have many interests, but you are not sure if there is one thing you wholeheartedly want to pursue.
Know that this is a process, and when the time is right you will know for sure what it is you need to do. Signs will begin to present themselves. At first they will be subtle, and later, crystal. As long as you are consistent in your alone time, honest reflection, and writing your answers will be revealed to you.
Affirm
Once you have the passion you wish (and need) to pursue, put it in affirmation form. Try this on for size…
“I am a talented painter, and my work is sought after from people from all walks of life.”
