Sant Satguru Kabir Sahib incarnated Himself in the guise of a human being on the full moon day of Jyeshat Sudhi (a great day falling on mid of May) in the year 1398 at Lahartara Talaab (a pond) in Kashi. At Lahartara Talaab, a bright white light from the sky appeared on a lotus flower and got emerged into a baby boy. During that moment Ashtanand Ji (Student of Swami Ramanand Ji) was meditating there at the nearby of Lahartara Talaab. He saw the incarnation happening, and was surprise to learn such an extraordinary miracle.
With full of surprise Ashtanand Ji reported the whole incident to his Guru- Swami Ramanand Ji. Hearing to such uncommon incident,Swami Ramanand Ji said that after a short while from now, whole world will soon come to know about this baby boy. And that boy became well known to the world by the name “Sant Samrat Satguru Kabir Sahib.”
The only objective of Kabir Sahib's own arrival onto the earth was to awaken each individual's Soul towards Satya Bhakti. For 120 years, He directed the world towards true worship of Supreme Lord (Param Purush / Sahib) which can only be realised by the grace of a real living Satguru.
Kabir Sahib disclosed all the secrets of so called "God of Universe ", who is no one else but, Formless Mind (Nirakaar Mann / Niranjan / Kaal Purush). He explained that all religions are worshiping the same "Formless God" in one way or the other i.e. in Sargun [God in Form] or in Nirgun [God as Formless] forms. He also gave the secret of Amarlok (4th Lok / Immortal Abode of Supreme Lord) to the humanity whose existence is beyond Universe (Trilok) and at the same time fought against hypocrites for the welfare of the humanity. He showed the path of permanent salvation which can only be attained with the blessings of a real living "Satguru".
Kabir Sahib has reformed the social structure of spirituality in right perspective. He has always been against hypocrites. He gave new dimensions to spiritualism through His ideology and teachings of Satya Bhakti, which became as the ideology of SantMat. The words Sant and Satguru came into origin from Kabir Sahib itself.
Kabir Sahib only spoke about Truth (Satya) which in itself was the reality that was unknown to the humanity and recommended to worship only Supreme Lord (Param Purush / Sahib), which was unacceptable to selfish spiritual leaders. He was the only Saint in the history of mankind who has been punished with 52 death sentences also known as Bawan Kasni.
Looking at large number of devotees following Kabir Sahib's Satya Bhakti, the selfish spiritual leaders were afraid of loosing their daily-means as well as their religious individuality. So they tried evil towards Him and created several wrong myths about Him. Some described Him as the offspring of an unmarried Brahman girl; others described Him as a child with uncertain identity and so on.
Even today, His birth and life is a mystery for the people of the world. Kabir Sahib himself has described this mystery i.e. Kabir Sahib has described His reality in His own words that:
Among Hindus and Muslims, Sant Satguru Kabir Sahib was a darling of both the communities. In the year 1518 at Maghar, Kabir Sahib declared that he would depart from the world on Magh Sudhi Ekadshi (An auspicious day falling on the next day of Lohri festival). General public along with devotees of Kabir Sahib gathered at Maghar on the date of His departure. Both communities claimed His body which was miraculously turned into lotus flowers. At last both the communities shared their portion of lotus flowers.
The following words were uttered at the time when Satguru Kabir Sahib left His body, which make us realise our foolishness in not giving due regard and recognition to the Holy Saints in their very lifetime.
