(31) By perfectly concentrated Meditation on the centre of force in the channel called the “tortoise-formed,” comes steadfastness.

(6) Let him firmly hold the body, head and neck erect, and gazing on the tip of his nose, without looking around, let him sit, serene and fearless, established in the vow of celibacy, self-controlled and balanced, thinking of Me as the Supreme goal.

(8) He who closes all the doors of the senses, confines the mind within the heart, draws the prāna into the head, and engages in the practice of yoga, uttering Om, the single syllable denoting Brahman, and meditates on Me— he who so departs, leaving the body, attains the Supreme Goal.

(6) Having abandoned all desires born of the ego-centric will, having restrained the group of senses with mind from all sides, one should attain quietude slowly and slowly by the intellect held firmly. And then, fixing the mind in Atma, he should not think of anything else at all.

(1) HE who would keep the rules must diligently guard his thought; the rules cannot be kept by him who guards not the fickle thought. Untamed elephants in their madness do not such harm here as the thought works in Avichi and the rest of the hells, a young elephant ranging free. But if the young elephant of thought be entirely bound by the rope of remembrance, all peril departs, and perfect happiness comes. Tigers, lions, elephants, bears, snakes, all foes, all the warders of the hells, witches and devils — all of them are bound, if only thought be bound; all are subdued if only thought be subdued. The Speaker of the Truth has said that from thought alone come all our countless terrors and griefs. Who has diligently forged the swords of hell, or its pavement of red-hot iron, and whence were born its sirens? All this has sprung from the sinful thought, as the Saint's song tells; thus in the threefold world there is no foe to fear save the thought. If the Perfect Charity frees the world from poverty, how could the Saviours of old have had it, since the world is still poor? The Perfect Charity is declared to be the thought of surrendering to all beings our whole possessions and likewise the merit thereof; thus it is but a thought. Where can fishes and other creatures be brought into safety, that I may not slay them? When the thought to do them no hurt is conceived, that is deemed the Perfect Conduct. How many can I slay of the wicked, who are measureless as space? But when the thought of wrath is slain, all my foes are slain. Whence can be found leather enough to cover the whole earth? But with a single leather shoe the whole ground is covered. In like manner the forces without me I cannot control; but I will control the thought within me, and what need have I for control of the rest? Though aided by voice and body, indolence can never win for its prize an estate such as that of Brahma, which falls to the lot of the vigorous unaided thought. The prayers and mortifications of a heedless and feeble man, however long he labour, are all in vain, says the Omniscient. To overcome sorrow and win happiness men wander in vain, for they have not sanctified their thcfught, the mysterious essence of holiness. Then I must keep my thought well governed and well guarded; what need is there of any vows save the vow to guard the thought?...
