“Demystifying Patanjali” was based on the wisdom of Paramhansa Yogananda presented by his disciple- Swami Kriyananda as a basis for a balanced Yogi to study. It is important to understand that these interpretations can somehow get mixed up. As far as 1-5 is concerned it is a complex Sutra and one that you should take your time with learning.
Vrittis= one’s self-developed inclinations (desires & attachments)
Some cause pain, some give pleasure.
*No self-definition can bring anyone happiness.
Sharing with others can only help to remove a layer of egoism from the giver’s consciousness.
We must try to overcome all self-definitions.
Our vrittis do not define us as we are; they only define us as we think we are.
We may tread the downward path to further suffering, or the upward, to eventual bliss in him.
Take what you can from each lesson and share your knowledge.
