Section 2 (stanzas 14-21). This section, quite diverse, had some reflections regarding the astral plane, the importance of selflessness: and a mystical imperative regarding the Kalahamsa.
Section 3 (Stanzas 22-40). The three halls, the hall of ignorance (physical plane), the hall of learning (astral plane), and the hall of wisdom (spiritual plane) and their relation to the four avasthas and the seven lokas. We learn that: ‘’The WISE ONES tarry not in pleasure-grounds of senses. The WISE ONES heed not the sweet-tongued voices of illusion’’. The hall of learning is full of delusional dangers, so one should seek one’s teacher in the hall of wisdom. The temptations of Mara are great and one needs to guard against the illusion of separateness. Finally, a type of Kundalini Yoga practice is presented, leading to the possibility of astral projection.
Section 4 (Stanzas 41-50)_is concerned with the seven mystic sounds, linked to the Nadabindu Upanishad and also the Hamsa Upanishad and Hatha Yoga texts. The 7-step ladder of mystics sounds of the inner God:
Based on the other yoga texts and stanza 50, I think it is plausible to assume that the 7 mystical sounds are related to the Chakras and Kundalini and 7 states of consciousness (and the 7 principles) accompanied by related Siddhis.
Section 5 (stanzas 51-65) deals with the heady business of the Higher Self conquering the lower self, which in Christian mysticism is called the path of purification. Ere thy Soul’s mind can understand, the bud of personality must be crushed out, the worm of sense destroyed past resurrection. (57) There was also a brief but eloquent call to compassion. But let each burning human tear drop on thy heart and there remain, nor ever brush it off, until the pain that caused it is removed. (61)
Section 6 (stanzas 66-78) deals with gates and ladders, a kind of prelude to a description of the seven stages, which seems similar to the eightfold yoga path.
Section 7 (stanzas 79-92) A kind of sevenfold Raja Yoga system is outlined, similar to the Eightfold yoga system, beginning with the Pratyahara stage, where a process of merging the five inner senses is explained. The next three stages correspond to the to three Sanyama practices. Upon achieving accomplishment in Samadhi, one becomes ‘’the doer and the witness, the radiator and the radiation, Light in the Sound, and the Sound in the Light’’.
Section 8 (stanzas 93-100), the final one, deals with the Four Noble Truths and the Five Hindrances.
