An interesting visual summarising Chap 1 to 6

The triangle

The triangles is the simplest shape as it takes only 3 lines to create a shape : an enclosed area

Well image these 3 lines to be
- The Object
- The Subject
- The Experience

The self is often caught between these 3 for all thoughts & actions

Now imagine the the lines opening at a point ...say we can disconnect the Experience from the Object  and then also from the Subject...would this be liberation !
Think about it...

Ref 18.18 and parts of Chapter 13 also talk about a similar Triad..

- The Object of Knowledge
- Knower of knowledge
- The Knowledge

PORT reduction

Possessions
Obligations
Relationships
Transactions

The above need to reduce gradually when on the spiritual path.

As per Gita if focussed on Karma Yog or Dhyan Yog or Bhakti Yog, this would happen naturally.
