Life on Earth and Life thereafter

Once again I wish to share my thoughts with you. When I was young, I never even thought of discussing this subject. I, obviously had to grow up with my guardians care and love. They groomed me the way they thought was right. and I grew up to a healthy young man. I had moral education from my parents and at the same time spiritual knowledge from the monks /priests. As I grew up, I fulfilled my wishes by living a very complex life. I had many interests and I ventured into the world of my dreams. I was attracted to the forbidden pleasures in life and got involved in many of their activities.
Today, at the age of 68 years, I realized that I had lacked in wisdom. I knew life as I lived and spiritually, I only believed the beginning and the end of life. For the past number of years, I sat down to think about life here on Earth and life thereafter. I read many books of life and listened to religious talks from various faiths, but I was not willing to accept the ideology of just BELIEVE.  I was told by my friends that if I really want to know what life is about, I should try to meditate.  So, I decided to learn how to meditate.
But what is meditation and how to meditate ? I made many enquires and different people taught to meditate in different ways. I thought meditation was simple and I did not make any effort to visit any meditation centre .  Well, I failed to concentrate every time I tried. The years gradually passed and yet I cannot achieve this way of relaxation. Some how and another, there was one time , I managed to sit for a while very relaxed. I was so comfortable and by the time I realized what was going on, 2 hours was gone. I was very excited and I continued this action regularly till today.
Although I have not found complete peace, but I have discovered the misfortune and misery I went throughout my younger days. This is the main reason I like to share my thoughts with you. I have come to many conclusions about life here and thereafter. Of course this findings of mine may bring many objections from others, but then these findings of mine is personal.
My findings are as follows :

1. This material world comes in two (2) sides which is the bright side and the dark side.
2.  Humans come in pairs
3  We have the good and the bad
4  Negative and positive
5  Temporary state of happiness and sorrow
6  This human body is temporary where else the soul and mind lives forever
7  So on and so on.

The 5 senses of ours lead us to creation and destruction as well.
The proper management of live brings us joy.
The renouncing of crave and the positive thoughts and action reduces dissatisfaction.

We should prepare ourselves for a good life on this planet and the spiritual world as well.
It is easier said than done, but if it takes a whole life time  to achieve such wisdom ,it surely is worth it.
I am so happy to share my thoughts of life with you and if you think otherwise, please advice me. I sincerely appreciate your loving kindness. Thank you.
