Yoga Vasistha says:~ Self-knowledge or knowledge of truth is not had by resorting to a Guru (preceptor) nor by the study of scripture, nor by good works: it is attained only by means of enquiry inspired by the company of wise (Gnani). One’s inner light alone is the means, naught else. When this inner light is kept alive, it is not affected by the darkness of inertia.
Advaita is universal. Advaita is not for Sale. Do not buy Advaita from the spiritual supermarket. Advaita is the nature of the Soul, the innermost Self. The world in which you exist is created out of single stuff. That single stuff is consciousness. Knowledge of the single stuff is Advaitic wisdom.
Advaitic truth is very simple, but it is very difficult to realize because you have accumulated mental garbage from different sources in the name of Advaita. Until you discard all the accumulated knowledge you will never be able to realize the Advaitic truth, which is beyond the form, time, and space.
The Advaita is the nature of the Soul, the innermost Self shines in its own its awareness when wisdom dawns.
The Advaita is the Soul is the cause and the support of all that exists as the world in which we exist. Advaita is the nature of the God, the innermost Self.
All accumulated knowledge accumulated through different Gurus and teaching theories path and practices has to be mentally burnt and start a fresh, if one wants realize the truth nothing but the truth. Serious and serious seekers are very few and they will get inner direction and able to reach the ultimate end of understanding and realization.
The majority of the seeker, are skin deep. They are happy with the person who emotionally satisfies their feeling. The truth pursuit is serious business. The urge to know the truth cannot be imposed on others. It has to sprout within. One need not search for the Guru because the Guru is within in to guide every seeker.
If you are aiming to be a master, Guru or teacher, you will never reach your destination. You have to share his knowledge with the fellow seeker not to make them his followers but only direct them if they are interested to travel beyond form, time, and space.
It is foolish to impose our idea on others because everyone is not in the same level of understanding. Everyone's inner work is on. When they are ripe enough they will understand, assimilate and realize on their own. If they are ready and sharp enough they will grasp it instantly and they will reach their destination with lesser time and effort. Thus, preaching, teaching is not wisdom, but by very careful reasoning, the seeker has to determine the nature of the reality. Deeper thinking and reasoning in the right direction alone helps seeker determining the nature of the reality, which is beyond the form, time, and space.
