Japji Sahib describes the basic concepts of Sikhism and is a manual for a Sikh to attain spiritual perfection.
The Japji Sahib is a Baani composed by Guru Nanak dev, the founder of Sikhism.
In Kundalini Yoga tradition, Sadhana begins with reciting Japji Sahib by all practicing.
It appears at the beginning of the Sri Guru Granth Sahib - Sacred Scripture of Sikh.
It favors participation in the affairs of the world, combined with an integration of wisdom and selfless activity.
It does not recommend passive contemplation or living an isolated life.
