PanchKoshas

The panch kosha are as under:

• Annamaya kosha

Related to food we eat

• Pranmaya kosha

Related to vital air.  Pranayam is about working on this kosha.

• Manomaya kosha

The dualities of life including sorrow and happiness, likes and dislikes are about this kosha/layer of life

• Vgyanmaya kosha

Spirituality starts from this kosha. One who has overcome annamaya kosha, pranmaya kosha and manomaya kosha starts this journey about spirituality.

• Anandmaya kosha

Each kosha/layer is subtler than the previous one. Pranmaya kosha is subtler to annamaya kosha, which is suttler to manoomaya kosha....

Being subtler means three things
subtle means nearer, subler means support suttler means more pervasive

it is support
Each kosha is superior to the former one. Pranamaya kosha is superior to annamaya kosha. Manomaya kosha is superior to pranamaya kosha.

We understand that mind is inside the body ...but in reality body is in air and both body and air is in mind and body , air and mind are in I.
