Helena Petrovna Blavatsky

“ And she will open wide before thee the portals of her secret chambers, lay bare before thy gaze the treasures hidden in the very depths of her pure virgin bosom. Unsullied by the hand of matter she shows her treasures only to the eye of Spirit—the eye which never closes, the eye for which there is no veil in all her kingdoms. ”

“ Having become indifferent to objects of perception, the pupil must seek out the Rajah of the senses, the Thought-Producer, he who awakes illusion.
The Mind is the great Slayer of the Real.
Let the Disciple slay the Slayer.
For--
When to himself his form appears unreal, as do on waking all the forms he sees in dreams;
When he has ceased to hear the many, he may discern the ONE—the inner sound which kills the outer. ”

“ Beware, Lanoo, lest dazzled by illusive radiance thy Soul should linger and be caught in its deceptive light.
This light shines from the jewel of the Great Ensnarer, (Mara) . [23] The senses it bewitches, blinds the mind, and leaves the unwary an abandoned wreck. ”

“ His vices will take shape and drag him down. His sins will raise their voices like as the jackal's laugh and sob after the sun goes down; his thoughts become an army, and bear him off a captive slave.
Kill thy desires, Lanoo, make thy vices impotent, ere the first step is taken on the solemn journey.
Strangle thy sins, and make them dumb for ever, before thou dost lift one foot to mount the ladder.
Silence thy thoughts and fix thy whole attention on thy Master whom yet thou dost not see, but whom thou feelest.
Merge into one sense thy senses, if thou would'st be secure against the foe. ”

“ Use them as they will thee, for if thou sparest them and they take root and grow, know well, these thoughts will overpower and kill thee. Beware, Disciple, suffer not, e'en though it be their shadow, to approach. For it will grow, increase in size and power, and then this thing of darkness will absorb thy being before thou hast well realized the black foul monster's presence.
Before the "mystic Power" [33] can make of thee a god, Lanoo, thou must have gained the faculty to slay thy lunar form at will.
The Self of Matter and the SELF of Spirit can never meet. One of the twain must disappear ”

“ When the disciple sees and hears, and when he smells and tastes, eyes closed, ears shut, with mouth and nostrils stopped; when the four senses blend and ready are to pass into the fifth, that of the inner touch—then into stage the fourth he hath passed on.
And in the fifth, O slayer of thy thoughts, all these again have to be killed beyond reanimation. [38] Withhold thy mind from all external objects, all external sights. Withhold internal images, lest on thy Soul-light a dark shadow they should cast. ”

“ The inner chamber of the Heart, called in Sanskrit Brahma-pura. The "fiery power" is Kundalini.
↑ (25) . The "Power" and the "World-mother" are names given to Kundalini—one of the mystic "Yogi powers." It is Buddhi considered as an active instead of a passive principle (which it is generally, when regarded only as the vehicle, or casket of the Supreme Spirit ATMA) . It is an electro-spiritual force, a creative power which when aroused into action can as easily kill as it can create. ”

“ Dharana, is the intense and perfect concentration of the mind upon some one interior object, accompanied by complete abstraction from everything pertaining to the external Universe, or the world of the senses. ”

“ The phenomenal World of Senses and of terrestrial consciousness—only.
↑ (18) The Hall of Probationary Learning. ["The Mind (Manas) which follows the rambling senses, makes the Soul (Buddhi) as helpless as the boat which the wind leads astray upon the waters" (Bhagavad-Gita II) .]
↑ (19) . The astral region, the Psychic World of supersensuous perceptions and of deceptive sights — the world of mediums. It is the great "Astral Serpent" of Eliphas Levi. No blossom plucked in those regions has ever yet been brought down on earth without its serpent coiled around the stem. ”

“ Says the same Nadavindu, "A Yogi who bestrides the Hansa (thus contemplates on AUM) is not affected by Karmic influences or crores of sins."
↑ (13) . Give up the life of physical personality if you would live in spirit.
↑ (14) . The three states of consciousness, which are Jagrat, the waking; Swapna, the dreaming; and Sushupti, the deep sleeping state. These three Yogi conditions, lead to the fourth, or—
↑ (15) . The Turiya, that beyond the dreamless state, the one above all, a state of high spiritual consciousness. ”
