திருமந்திரம் - 9 தந்திரங்கள் > சுட்டுக
“ I reached my Sahasrara and found the Holy one seated there. Many do not know how to search for the Lord like this . I ascended from Mooladhara through Sushsumna to reach Brahmarandhra. There I witnessed the Swarupa of the Lord. The Divine darshan gave me the vision of the World.”
“After crossing the Nine stages (7 chakras & Nada & Bindu) , I reached the City of Siva and His consort, Sakthi and performed Puja to the Lotus feet with pure Wisdom.”
