When I think of how everyone can simply be happy, I usually think of some fundamental layers which need to exist to build the foundation of your happiness.

These layers are not 'really' layers but a simple way to comprehend the concept of the interdependent components.

All these layers needs to be taken care of on a daily basis.  What I mean by 'taken care of' is that we need to pay attention to these layers by doing things which are appropriate for each of the layers so that the layer remains strong.  If we don't, the layer deteriorates and causes the Happiness Stack to fall apart.

It is like not watering our favorite plant. The plant can probably go up to a couple of days without water. But after some time its health will start deteriorating. 

So what layers does the Personal Happiness Layer comprise of :

Physical layer  ( the body)

Energy layer  ( breath, food , rest)

Mental layer  ( your thoughts and related feelings)

Intellectual layer ( your knowledge based activities which accesses memories and experiences) 

Awareness layer ( the pure consciousness)

Each of the layers can interact with any other layer and that is the key thing to note here.

Supreme happiness (Bliss) is attained when all these layers work efficiently and interact properly.

This concept of 'happiness layers' is not something I invented. In fact, it has been around for ages. The hindu tradition (from India) labels its the 5 sheaths of human existence

Anna-maya kosha  - Organic body

Prana-maya kosha - Energy body

Mana-maya kosha -Psychic body, thoughts and feelings

Vigyana-maya kosha -  Intellectual body, spiritual discrimination and wisdom

Ananda-maya kosha - Body of joy, pure consciousness, blissful being
