Path of spiritual wisdom requires renunciation (त्याग) and Shiv ji is Acharya of path of spiritual wisdom.
By following the path of Spiritual Wisdom, Gyani experiences that body and jivatma, both are different. Gyani does not have attachment to anything or anybody. He does not accumulate things. His birth is for tapas. By tapas, one gets purified.
Role of Satsang:
To attain spiritual wisdom, satsang is necessary. Hence, satsang should be every day. It purifies manas (मन). Saints always remember-meditate on the almighty.
Yoga vashisht Ramayan has explained seven stages / roles of wisdom viz.
Great desire of auspiciousness (शुभेच्छा), Positive investigation (सुविचारणा), Tanumanasa (तनुमानसा), Sattvapatti (सत्वापत्ति), Dissociation (असंसक्ति), Pdarthbhavini (पदार्थभाविनी) and Turiga (तुर्यगा). These are explained as follows:
The first three roles in the seven roles are “instruments or means excellence” (साधनकोटि) and the remaining four are “wisdom excellence” (ज्ञानकोटि). During first three stages, one need to meditate over Brahman with attributes i.e. personal god. Reaching to fifth stage, the chord between body and consciousness (jivatma) starts breaking and one starts experiencing jivatma. At this stage, one dissociates more and more from body presence.
