We all desire happiness, but what is it truly and how to reach it surely and personally?

Question

If we learn to know exactly what is happiness and act with spiritual guidance, we will surely obtain it.
"So Bahá'u'lláh made the utmost efforts to educate [His people] and incite [them] to morality, the acquisition of the sciences and arts of all countries, kindly dealing with all the nations of the earth, desire for the welfare of all peoples, sociability, concord, obedience, submissiveness, instruction of [their] children, production of what is needful for the human race, and inauguration of true happiness for mankind; and He continually kept sending tracts of admonition to all parts, whereby a wonderful effect was produced. Some of these epistles have, after extreme search and inquiry, been examined, and some portions of them shall now be set down in writing.
All these epistles consisted of [exhortations to] purity of  42  morals, encouragement to good conduct, reprobation of certain individuals, and complaints of the seditious."
(Abdu'l-Baha, A Traveller's Narrative, p. 41)

Follow these Spiritual Laws and you will find nothing but Happiness and Success in life : )
If you are not happy, have a look at your life to see what you need to change to make yourself happy
Life is what you make it : )

Seven Spiritual Laws of Success

1. The Law of Pure Potentiality
The source of all creation is pure consciousness... pure potentiality seeking expression from the un-manifest to the manifest. When we realize that our true self is one of pure potentiality, we align with the power that manifests everything in the universe.

2. The Law of Giving
The universe operates through dynamic exchange.... giving and receiving are different aspects of the flow of energy in the universe. And in our willingness to give that which we seek, we keep the abundance of the universe circulating in our lives.


3. The Law of Cause and Effect
Every action generates a force of energy that returns to us in like kind.... what we sow is what we reap. And when we choose actions that bring happiness and success to others, the fruit of our action is happiness and success.

4. The law of Least Effort
Nature's intelligence functions with effortless ease.... with care-freeness, harmony, and love. When we harness the forces of harmony, joy, and love, we create success and good fortune with effortless ease.

5. The Law of Intention and Desire
Inherent in every intention and desire is the mechanics for its fulfillment... intention and desire in the field of pure potentiality have infinite power. When we introduce an intention in the fertile ground of pure potentiality, we put this infinite organizing power to work for us.

6. The Law of Detachment
In detachment lies the wisdom of uncertainty..... in the wisdom of uncertainty lies the freedom from our past, from the known, which is the prison of past conditioning. in our willingness to step into the unknown, the field of all possibilities, we surrender ourselves to the creative mind that orchestrates the dance of the universe.

7 The Law of Purpose in Life
Everyone has a purpose in life... a unique gift or special talent to give to others. When we blend this unique talent with service to others, we experience the ecstasy and exultation of our own spirit, which is the ultimate goal of all goals.
