Not kundalini yoga but Jesus Christ definitely indulged in activation of kundalini to reach state of enlightenment. It is quite possible that Jesus never went after kundalini awakening. His love for mankind, his desire of meeting God activated his kundalini fully totally unknown to him.
State of enlightenment could not be reached in absence of full kundalini awakening. As Jesus Christ was an enlightened one, his kundalini had definitely awakened fully.
Seekers, travelers of spiritual path were always after wisdom contained in Bhagavad Gita and Upanishads (independent spiritual treatises). During the missing years in the life of Jesus Christ (age 14 to 29) Jesus Christ came to India (erstwhile Bharatvarsha) to indulge in Indian form of spirituality contained in Bhagavad Gita. Upanishads even Vedas (the first words of God revealed to mankind).
For a full kundalini awakening practice of absolute celibacy for minimum period of 12 years in continuation is necessitated. Jesus Christ would have accomplished this during his stay in India (erstwhile Bharatvarsha). All the wisdom of Jesus Christ has its roots in erstwhile Bharatvarsha. Christianity may acknowledge or not but rightful events in the history of mankind cannot be belied.
Every single spiritual seeker in search of God indulges in full awakening of kundalini shakti. That is how one activated the major dormant lying portion of brain. Normal human beings used their brain 1 to 2%; enlightened ones used their brain 100%.
As our kundalini activated in stages proportional was the activation of brain. Full 100% activation of brain means one reaching state of enlightenment forever.
On path of pure spirituality practicing absolute celibacy for a period of 12 years in continuation played a very vital role. Physical aspect of celibacy (abstention from sexual indulgence) played a very minor role, 90% celibacy was always practiced mentally. Eradicating flow of negative thoughts to our brain in totality is what absolute celibacy all about.
Jesus before coming to India very well knew that Indian spirituality contained more than he bargained for. The irony of Christianity is that none other than Jesus Christ in western world ever tried to become a Jesus Christ in real life. In Hinduism not one or 10 but in hundreds seekers succeeded in reaching stage of enlightenment.
All the 24th Tirthankaras of Jainism (preceptors) belonged to erstwhile Bharatvarsha. Followed them Gautama Buddha, then Adi Shankaracharya and in recent times Sri Ramakrishna Paramhansa and Maharshi Ramana.
The beauty of Hinduism and also Jainism is their scriptures openly say that every single human being in entire world had the inbuilt capability to become a Mahavira, Gautama Buddha even Jesus Christ or Prophet Mohammed in real life. As per Hinduism scriptures every single human being has to finally reach state of enlightenment. We can do it in present life time or keep it pending for future manifestations undertaken by our soul atman.
Jesus Christ decided to do it in his lifetime and finally succeeded in gaining enlightenment. His practice of absolute celibacy resulted in full awakening of kundalini shakti.
