Every individual is born into a religion that is practised by the family he is born into in this incarnation. The journey of the soul is to eventually merge back into the divine. God is love and god can be found with devotion alone also.There is a power behind this creation which is creating it and sustaining it. 

God is formless and yet he has thousands of forms because he is in all creation that he has created.God is calmness, peace, love, bliss , light, sound,power, wisdom, these are the eight aspects that god can be experienced in.

The above statements can be related to by many and many would not be able to relate to depending upon the stage at which the soul is at its Karmic journey. But the statements made below will be relatable by all whether they are a little short of God realisation or far from that. 
What We all humans want in this incarnation  can be summed up as - good health, we want to be prosperous and we want to be happy.
The above three will embrace all humanity in it , more or less.
To what extent of good health , what is my highest potential of prosperity, what will give me happiness and how are the questions which we seldom ask and if we do we will move in the direction of wanting to achieve our highest human potential. ( Mann tun Jyoti Swaroop hae , Apna mool pehchaan )

To operate any gadget we get a user manual which we are advised to refer to so that we can use the gadget and also use the gadget to its full potential.

Likewise for the gadget called Human being the user manual is the teachings and instructions written in the scriptures. Truth is one and eternal and all the saints and sages have preached the same. Those who want to verify can embark on the lovely journey of comparing the scriptures which so many sages have done before.( Paramhansa Yogananda ji being one of them)

Given this wide spectrum of merging back with god on one side and how to be healthy, prosperous , how to be happy - which we are when our relationships are good, we are calm and not tensed , able to achieve our goals whatever they may be , like when in youth doing well in studies, doing well in games, having good friends, All the sub points and the top point that fall in this spectrum can be achieved by learning and implementing the teachings of the scriptures.

Now the question comes that how to understand and implement the teachings of any scriptures, this is where Kriya Yoga comes in , Kriya yoga is a scientific guru given technique ( pranayama )of burning the seeds of karma to help a human being realise his higher potential.
Kriya Yoga Teachings of Paramhansa Yogananda are available online and offline , being offered by Ananda Sangha. In Punjab there are two centres , Chandigarh and Ludhiana where these teachings are being shared in offline mode. 

Kriya Yoga
My favourite book is autobiography of Yogi. In this book, kriya yoga is explained beautifully. If we consider it scientifically, in this technique, the human blood is decarbonized and recharged with oxygen. The atoms of this extra oxygen are transmuted into life current to rejuvenate the brain and spinal centres.  
Elijah, Jesus and Kabir and other prophets were past masters in the use of Kriya or a similar technique, by which they caused their bodies to dematerialise at will. 
The Kriya Yoga is a revival of the same science which Krishna gave millennium ago to Arjuna, and which was later known ito Patanjali and to Christ , Saint John, Saint Paul and other disciples. 
The Kriya Yogi mentally directs his life energy to revolve upward and downward, around  six spinal centres which corresponds to the 12 astral signs of the zodiac. He uses this technique to saturate and feed all his physical cells with light and keep them in a magnetized state.
