Enlightenment is nothing but remain centered in pure awareness. It is the state of being in which you listen silently. Normally in a class room we listen to speech. If you can listen to silence within yourself it is called enlightenment. External noises don't disturb you but deepen your silence and awareness.

We might have felt such moments, when we see a vast space, beautiful scenario. But they will be momentary only. Again when we return to our normal life we have same worries and troubles.

It is not the environment has given you peace but your inner state is the key. Whenever You don't have thoughts or emotional blocks you will be in peace irrespective of outside factors.

So all meditative techniques focus on bringing thoughtless moments and give a glimpse.You will forget about body also just immersed in vast sky like feeling.

Many psychological techniques are used to relieve from burden of thoughts and emotions of past.If you are not worrying too much about the future or past and be aware in present moment you will be in peace.

Beliefs will be dropped with proper Questioning and discrimination. With this you come out of religious,social,cultural conditioning. You don't need to worship or pray or chanting mantras for attaining peace.

You will be deciding moment to moment, not based on past conditioning but out of understanding and proper analysis when needed.

The Peace is not based on any sensual pleasures.When you close your eyes, shut your ears also, peace will be there.But it doesn't mean that sensual pleasures are not necessary or sin.You will come to know that peace is only a state of inner being, irrespective of your place of living,monetary conditions, social status,position of power.

You will feel that peaceful moments are more blissful than moments of sensual pleasures. Just you are alert and in a witness state.

Because you are in highest state , you will be in Love with others, accepting others as they are ,patiently waiting but not forcing others to your way. Also even if you see others are enjoying more sensual pleasures than you ,you won't feel envy and wasting your energies in fighting or competing because you are more than that.

Peaceful witness state is beyond our physical,mental, emotional state.You will feel that you are centered.You will feel this witnessing consciousness is static, while body, mind, emotions change from moment to moment.

After attaining or realizing and centered in witnessing state, it doesn't mean that you won't feel any physical pain or suffering. Just you will be centered irrespective of pain and pleasure.

You come to know that nobody or any objects is yours, because you won't take it after death. It is just our attachment while living.It is just dreaming.

Marital relationship based on mutual respect, love and Trust will last longer. Actually you have to build the relationship. Just because you married, it doesn't mean that it will be a happy relationship.If you won't go any personal transformation, changing partners is not going to provide you happiness. Since you are not transformed ,soon or later you come to know that you are selecting similar person only in terms of psychology.This is true for every relationship.

Good proper and enough food and exercise is needed to keep the body health. Good understanding and Intelligence is needed to avoid unnecessary troubles. Good Human relationship is needed to be in harmony with others. Scientific approach is needed in dealing with objective world.

If not, even you are in meditative state, body,mind and emotional troubles will be there. So holistic approach is the wise approach.

Materialization is only a magic trick performed by skilled magicians who know deep psychological and scientific rules in deception.
