Sir, you have been talking and writing about all the subjects bravely and clearly. Who has offered you so much of strength and courage? If asked shortly, who is your guru?
There is a verse in Sanskrit language :
Sasthiram saareeram meemaamsa devasthu parameswara!
Aachaarya ramakrishnaaya santhume janme janmane!!
This means that I will take birth in this world for any number of times if the principle followed by me is the ethics said in the Meemamsam (set hindu philosophical principles), if the god worshipped by me is the Lord Parameshwara, if the person who is guiding me is Guru Ramakrishna Paramahamsa.
I consider the great legend Shri Ramakrishna Paramahamsa as my essential guru, who is guiding me by being present in my mind and also in my soul a virtual guru, who is spread all over my blood in every cell, who is a guide to me even today, in my saint life.
While I have identified sadly about the true characters of few people, who have reject to give me life showing my physical disability as the main reason, I have recognized and deemed his highness Mahaguru Devar Shrimad Rudra Paramahamsa as my virtual guru who has offered, blessed me with a life similar to a mother who consoles a crying child with hungry.
Apart from these two great people, I have various gurus or teachers in every field. Moreover, I consider and respect any person as my guru or teacher, who says or teaches me about a matter not known to me.
I consider all the people as my guru or teacher the released prisoner, whom I met in the railway station, detailed me about his life in the jail, the great siddha guru named Oomaiyan, who has taught all the techniques from Parakaaya pravesam to the kundalini yoga.
There are no limitations about the appearance or the form of the teacher or guru. We can feel if we keep our eyes open that the insects like the creeping caterpillar to the flying bird will teach us various topics.
All the advisors are the teachers. We have to focus on the subject rather than the eligibility of the advisor. This will only be the root cause to the mind and the development of knowledge.
PS : Parakaaya Pravesam -- The power to leave your body consciously and enter into a new one
Kundalini : Kundalini as lying "coiled" at the base of the spine, represented as either a goddess or sleeping serpent waiting to be awakened. In modern commentaries, Kundalini has been called an unconscious, instinctive or libidinal force.
Kundalini yoga --- A focus on awakening kundalini energy through regular practice of meditation, pranayama, chanting mantra and yoga asana
