Activation of third eye also called Ajna chakra results when we awakened kundalini energy fully. Awakening of third eye is the goal, precept and indulgence in kundalini awakening the path.
Indulging in Indian spirituality as detailed in Bhagavad Gita and also Upanishads (independent spiritual treatises) we can awaken our kundalini shakti fully. Kundalini could not be awakened by any other path other than assimilating teachings of Lord Krishna contained in Bhagavad Gita.
The wisdom in Bhagavad Gita was without a parallel, contains A to Z of spirituality. If our goal of life was spiritual there was nothing better than following precepts of spirituality detailed in 700 shlokas verses contained in Bhagavad Gita.
What’s more the original 700 shlokas verses in Sanskrit along with English transliteration are available for mere $1 from Gita press, Gorakhpur, India. So economical yet in the last about 150 years amongst 7000 million people existing world over only Sri Ramakrishna Paramhansa and Maharshi Ramana succeeded in full activation of third eye.
The path of kundalini awakening, activation of third eye is not easy to travel. One must indulge in kundalini awakening only if our goal of life was meeting God in present life time. Those who related to religion (path of rituals) must never indulge in anything called kundalini awakening or third eye. Path of kundalini awakening was only meant for seekers travelers of spiritual path.
Indulging in spirituality when human beings start their kundalini activation in stages step-by-step, chakras existing in our spine opened gradually. The moment we reached Ajna chakra, Sahasra Pushpa (thousand petalled Lotus) existing in our brain behind forehead opens fully. This opening of Sahasra chakra in totality is called opening of third eye, activation of sixth sense in totality.
The moment third eye activates one immediately gains enlightenment becomes an enlightened one forever.
The activation of the kundalini from base of spine to sixth chakra also known as Ajna chakra is ordained by God to be completed in many lifetimes. To accomplish the same in a limited time span of 70 to 80 years of earthly life, willpower exhibited by Swami Vivekananda is necessitated.
For spiritual travelers one thing is very soothing to our intellect that all spiritual gains were always permanent, nothing could ever be reverted back including partial kundalini awakening.
As partial kundalini awakening was such potential energy that it could cause havoc in life, seekers travelers of spiritual path must undertake spiritual journey with caution.
Opening of third eye means becoming a Mahavira, Gautama Buddha and Jesus Christ or Prophet Mohammed in real life.
