One of the Laws of Nature is that nothing happens by accident in this world. This is also known as the Karmic Law.

Perhaps it is easier to give one an explanation using examples. Grasses and trees grow continually. If a sunflower seed is sown, sunflowers bloom. If a morning glory seed is sown, morning glories bloom. When one sows a sunflower seed, one never expects a morning glory to bloom.
The Karmic Law works exactly the same. If a good seed is sown in one's thought, a good result follows. If a vicious seed is sown in one's thought, one should expect a vicious flower to bloom.

Every event happening at the present time is attributed to what you thought and how you behaved in the past.
People oftentimes believe that praying to God brings one good fortune but that is a not perfect understanding. Actually, when one prays while one's body and mind are completely relaxed (a meditative state) and one chants or contemplate the same prayers repetitiously,  the thoughts in the prayer reach the subconscious world, which retains A massive record bank (also known as "collective consciousness" or "Akashic Records") and eventually manifest itself in this materialistic world as realization.

The subconscious world does not judge whether one's thought is good or not, nor advise one to discard bad thoughts - yet it is left to the individual to chose and be responsible for what thoughts are delivered.

In one of the scenes from the movie "Star Wars", directed by George Lucas, the Master, who is responsible for making the universe harmonious, states "There is no TRY. DO or DO NOT."
Here, trying indicates your admission that you do not possess sufficient means within yourself to achieve your purpose at the present time.

For example, if you think "Love" is important, you decide to take action either by
(1) I try to give Love; or
(2) I do give Love
Let us examine the difference between these two conceptual approaches.
(1) At the moment, I do not possess love, however I will make an effort to give love. In other words, when I realize Love, I will give Love. It is a conditional action.
(2) I am in possession of love. I choose to give Love no matter what. Since you already possess love, it is easy to carry out the action.

Another example is a "wish to become rich." You are not presently rich so when you say "I am rich", your true state of mind resists it because your subconscious knows you actually are not. Then, according to Murphy's Law, these negative thoughts in your subconscious mind manifest themselves and the opposite occurs. However, when you say "I will try to become rich", you admit that not only are you not presently rich but also that you have no potential of becoming rich. In order for your to admit the possibility of becoming rich, you must believe that you possess that potential to become rich and you must convince yourself that you are going to be rich.
When your belief gains enough strength to reach the subconscious state, it manifests itself in this reality as would a sown seed grow, bloom and bear fruits.

Therefore, in conclusion, one should accept things as they are in the present and choose to send good thoughts in his prayer to reach the subconscious state, which will create a fruitful, harmonious, peaceful and happy life.
