2°) PRANI PATENA - Comprises the disciples identified by this term; that is, those who surrender to their Master confident in their Sraddha or faith in his wisdom, which will guide them safely through the steep slope, "SO NARROW AND SHARP AS THE EDGE OF A RAZOR," —the Upanishads said— sure guide and free from errors and powerful help for the disciple regarding the development of a strong will, full of celestial knowledge, whose pedestal rises in infinite love professed by The Master, who will undoubtedly make him capable of discovering "The Lamp of Wisdom" (Jnana Dipa) hidden in the most recondite of himself (Atma Stham) by the light of his own conscious perception, (Viveka) to protect it from the weak glow of his passions, transmuting these into pure love and austerity (Vairagya and Tapas); and finally, through concentrated contemplation (nitya pravritta aikagrya dhyana) he kindles the brilliant flame of direct cognition and, therefore, his identification with the SELF. (Samyak darshanabhas).
3°) SEVAYA - Finally, those who respond to this grade are the disciples denominated with the word "Service." They are those who have verified that the true remedy against the great obstacle to spiritual progress—Swartha or self-isolation—is found in the practice of Sarvartha or Universalism, and they give themselves with full heart to the service of their brothers, whose service is offered to the Masters, who have as emblem a single and beloved word: HUMANITY.
THE HIERARCHICAL ORGANIZATION
Hamsa Yogui explains then that the spiritual Masters of high rank described in the verse as Jnamis and Tatvodarshis (Masters of Wisdom and Seers Knowers of Truth) do not undertake directly the preparation of aspirants of the first grade mentioned above, but rather, assign this duty to Initiates of rank inferior to them.
This explains why the blind King was put under the tutorship of Sanjaya.
In sum, we can resume this fact in the following form:
The conversations between the King and Vyasa on the occasion of the latter's visit, simply demonstrate to us that the King had made true efforts to reach the meaning of the teachings existing in the Scripture, and that he reunited intellectual conditions and competence for spiritual training.
But it was also evident that he found himself under the influence of his egotistical isolation—Swartha—which prevented him from being taken under Vyasa's direct supervision.
As a consequence of such state, it was necessary to consider the King in the conditions of disciple of inferior class, in charge of an initiate of Sanjaya's rank, who, through the grace conceded by Vyasa, had acquired not only complete efficiency in Sastric science and in the development of the powers of clairvoyance and clairaudience, but also reached Union with the Divinity.
