"Krishnamacharya went searching for the ashram of Rama Mohana Brahmacari. In a cave, a very tall hermit with a long beard, wearing wooden shoes stood at the entrance. It was evident to Krishnamacharya that this was his guru. He prostrated before him, gave his name and asked to be his disciple. Krishnamacharya was questioned in Hindi on the reason for his visit. After he expressed his desire to learn yoga he was called in. He met his guru's wife and three children. he was given fruits called Ankula to eat and the escorts who accompanied him were dismissed with a cup of tea.
Krishnamacharya's first instruction from his guru was, to take a bath and perform acamana. The first precept of pranayama was then taught. For eight days, the master said he would not teach him anything else and that Krishnamacharya should eat only fruits.
Thereafter Krishnamacharya became a part of the Rama Brahmacari's family who belonged to the Kasyapa gotta (family lineage). His daily food was chapathu (Indian bread), halwa ( a paste of vegetable or fruits sweetened along with ghee and tea). His period of gurukulam (stay with the guru ) in Tibet lasted for seven and a half years. Rama Mohana Brahmacari made him memorise the entire Yoga Kurantam in the Gurkha language. The various stages of Patanjali's Yoga Sutra were dealt with in that book. Various kinds of of yoga practises were also described with great clarity. Only with the help of Yoga Kurantam' could he understand the inner meanings and science of the Yoga Sutra. The first three years he was made to memorise the Yoga texts in the form of adhyayanam ( to memorise and recite correctly, with proper accents). His focus was in the study of the Yoga Sutra, Vyasa Bhasya and the Samkhya Darsana. In the next three years he practiced yogabhyasa and for the next one and a half years he studied the siksana krama (planning of practices based on the stage of life of an individual) and the cikitsa krama (therapeutic approach).
During his seven and a half year stay with his guru, Krishnamacharya learnt all aspects of yoga practice, therapy and philosophy. His capacity to learn, his previous education and his discipline made him an ideal student.
Having spent seven and a half years with his guru he would happily have spent the rest of his life learning and serving him but Rama Mohana Brahmacari then told him to go back to society, lead the life of a married man and spread the message of Yoga. Following his guru's words he returned from Tibet in 1922"

I did not attempt a detailed review of all ancient yoga treatises since it will make this book very long and perhaps cause boredom to the readers. Please forgive. This writing is mainly based on the following texts:
Upanishads related to yoga
Learning’s from my Guru and self-experience
