The path to the Self leads through many unknown territories in the subtle realm as the aspirant penetrates through the energy sheath and the mental sheaths. It is important for the aspirant to first grasp the context in which these original teachings were formulated, so that a better appreciation is gained of the need to respect these cautions. In the ancient texts, these points are not always articulated clearly because these practices were always meant to be performed under the direct supervision and in the continuous presence of a realized master, or Guru. The disciple lived with the Guru so there was always a competent teacher to guide the student on a daily basis and provide help as and when it was needed. The Guru had not only mastered the path to the Self, but knew how to lead students of different levels and backgrounds, and was familiar with necessary procedures in case of spiritual emergencies. The commitment of a Guru to a shishya (disciple) was not just one of a teacher and a student. The Guru was firmly committed to the welfare of a shishya in every way, and would move heaven and earth to enable the sincere student to reach the goal. These days it is hard to find aspirants or Gurus of that caliber. However, this does not mean that aspirants should not practice, or seek whichever guide or teacher they find to be appropriate. But it is more important these days to explicitly state the caveats and reasons for caution on the path.
There are good reasons why these practices were held secret for many centuries: the intent was that only those who were adequately prepared and trained should embark on the path. It was not to withhold the truth from anyone. This has been misunderstood by many newcomers and they are freely posting mantras and associated practices for anyone to try without taking the pains and care to judge the preparation of the aspirant.Â
