Path of Knowledge, the Atman (Bhagavad Gita 2) Jnana Yoga (Brain to Conceive)
Training: Bhagavad Gita Course - Karma Yoga Course - Master in Bhagavad Gita
Chapter 2 - Yoga of Knowledge (Sankhya) of the Bhagavad Gita is dedicated to this path, where Sri Krishna said to Arjuna:
“Sri Krishna: Assume victory and defeat equally, and prepare for the fight; so you will not commit without. Thus I have set before you the Path of Knowledge (Samkhya)” Bhagavad Gita 2.38.
Jnana in Sanskrit means knowledge, and marks the path for those reflective people, who have the continuous need to think. This path is the most difficult of all.
In chapter Yoga of Action (Karma) of the Bhagavad Gita, Sri Krishna said to Arjuna:
“I have spoken to you about two attitudes in this World: that of the Sankhayas, for yoga of Knowledge (Jnana) and that of the yogis, for Karma Yoga (Yoga of Action). Man never enjoys freedom from action by not undertaking it, nor does he attain that freedom by mere renunciation of action” Bhagavad Gita 3.3-4.
For Swami Vivekananda, Jnana Yoga is the path of wisdom, whoever seeks to unite with the Supreme Person: God, Brahman, Sat-Chit-Ananda, Allah or whatever you want to call him, through philosophy and inquiry is a Jnani Yogi:
“Karma Yoga is suitable for the man of active temperament. Bhakti Yoga for the devotee. Raja Yoga for the mystic. Jnana Yoga (Yoga of Knowledge) for the philosophical.”
The Bhagavad Gita according to Swami Vivekananda
For Swami Sivananda:
Jnana Sankhya Yoga: Conocimiento Atman 
Jnana Sânquia-ioga.
