Volume IV - Part 3
I do not think X’s trance has anything to do with her ill health; I have never known the habit of trances of that kind to have any such result, only the violent breaking of a trance might have a bad result though it would not necessarily produce a disaster. But there is the possibility that if the conscious being goes out of the body in an absolutely complete trance, the thread which connects it with the body might be broken or else cut by some adverse force and it would not be able to return into the physical frame. Apart from any such fatal possibility there might be a shock which might produce a temporary disorder or even some kind of lesion; as a rule, however, a shock would be the only consequence.
The general question is a different matter. There is a sort of traditional belief in many minds that the practice of Yoga is inimical to the health of the body and tends to have a bad effect of one kind or another and even finally leads to a premature or an early dropping of the body. Ramakrishna seems to have held the view, if we can judge from his remarks about the connection between Keshav Sen’s progress in spirituality and the illness which undermined him, that one was the result and the desirable result of the other, a liberation and release from life in this world, mukti. That may or may not be; but I find it difficult to believe that illness and deterioration of the body is the natural and general result of the practice of Yoga or that that practice is the cause of an inevitable breakdown of health or of the final 
illnesses which bring about their departure from the body. On what ground are we to suppose or how can it be proved that while non-Yogis suffer from ill health and die because of the disorders of Nature, Yogis die of their Yoga? Unless a direct connection between their death and their practice of Yoga can be proved – and this could be proved with certainty only in particular cases and even then not with an absolute certainty – there is no sufficient reason to believe in such a difference. It is more rational to conclude that both Yogis and non-Yogis fall ill and die from natural causes and by the same dispensation of Nature; one might even advance the view, since they have the Yoga Shakti at their disposal if they choose to use it, that the Yogi falls ill and dies not because of but in spite of his Yoga. At any rate, I don’t believe that Ramakrishna (or any other Yogi) fell ill because of his trances; there is nothing to show that he ever suffered in that way after a trance. I think it is said somewhere or he himself said that the cancer in his throat of which he died came by his swallowing the sins of his disciples and those who approached him: that again may or may not be, but it will be his own peculiar case. It is no doubt possible to draw the illnesses of others upon oneself and even to do it deliberately; the instance of the Greek king Antigonus and his son Dimitrius is a famous historical case in point. Yogis also do this sometimes; or else adverse forces may throw illnesses upon the Yogi, using those round him as a door or a passage or the ill wishes of people as an instrumental force. But all these are special circumstances connected, no doubt, with his practice of Yoga; but they do not establish the general proposition as an absolute rule. A tendency such as X’s to desire or welcome or accept death as a release could have a force because of her advanced spiritual consciousness which it would not have in ordinary people.
On the other side there can be an opposite use and result of the Yogic consciousness: illness can be repelled from one’s own body or cured, even chronic or deep-seated illnesses and long-established constitutional defects remedied or expelled and even a predestined death delayed for a long period. Narayan Jyotishi, 
a Calcutta astrologer, who predicted, not knowing then who I was, in the days before my name was politically known, my struggle with Mlechchha enemies and afterwards the three cases against me and my three acquittals, predicted also that though death was prefixed for me in my horoscope at the age of 63, I would prolong my life by Yogic power for a very long period and arrive at a full old age. In fact I have got rid by Yogic pressure of a number of chronic maladies that had got settled in my body, reduced others to a vanishing minimum, brought about steadily progressing diminution of two that remained and on the last produced a considerable effect. But none of these instances either on the favourable or unfavourable side can be made into a rule; there is no validity in the tendency of human reason to transform the relativity of these things into an absolute.
Finally I may say of X’s trances that they are the usual savikalpa kind opening to all kinds of experiences, but the large abiding realisations in Yoga do not usually come in trance but by a persistent waking sadhana. The same may be said of the removal of attachments; some may be got rid of sometimes by an experience in trance, but more usually it must be done by persistent endeavour in waking sadhana.
