1) After Kundalini awakening you become susceptible for Energy, Frequency changes. So If you don't built equanimity , you keep reacting to life intense situations between hatred or love. You swing like a rollercoaster.

2) Most intense energy experiences like kundalini happens during RAHU MAHADASHA in your astrological chart. I had many natal charts preview ,RAHU brings spiritual dimension, this is the time to learn to understand true nature. If you feel totally engrossed by such experiences , then you can do RAKTACHANDAN , GOMED to calm the rising pulses of RAHU energy .

Remember BUDDHA left his home for spiritual attainment during RAHU mahadasha

3) Always focus being equanimous in all life situations. Start with building mindfulness practice. All spiritual texts tells you to live life in a balance wau, not to dangle between love- hatred , craving aversion. GEETA , BHAGWAT , 8 WHEELS OF DHAMMA, GHERANDA SAMHITA ( Father of HATHA YOGA) all speaks about calming your mind. Some just use mind training as the primary way , some use physical aspects like yoga ( because majority of people are physical & sensation driven ), Shatkarma , Yama , Niyama . Remember Patanjali , Gheranda rishi has put Dharna & Dhyana as their ultimate goal after Yoga & Pranayama. SO everyone wants you to reach upto the level of Dhyana after Asanas.

We should learn to build equanimity in our lives , that is the core essence of all practices. The more you learn such fancy terms ( Dark Night Of the Soul) it just traps you in a mindset .
