In discussing samadhi, it has to be recognized that descriptions of yogic states, not part of ordinary experience, will be increasingly unsatisfactory when judged by ordinary experience and its standards.
A man who has never seen the sea will find descriptions of it increasingly incredible; he who has only seen ripples on a little lake will not be able to accept stories about waves eighty feet high round Cape Horn.
To get a hint of samadhi, a student is recommended to create particular circumstances favourable to it.
He should get up early and be sitting comfortably on a hill looking towards the east, half an hour before dawn on a clear morning, to watch the sun rising.
It is essential that he should not see anything close to him in the line of sight; that sets up reactions in his body.
He may be unconscious of them but they can prevent the experience.
His vision should go out to the far distance; if he cannot find a hill, he can look out over the sea on a calm day.
He watches the lightening of the sky before the dawn, then the edge of the sun coming up, then the whole orb. It is often found on these occasions that there is a partial loss of body consciousness, and absence of the verbal associations ‘sun’, ‘sea’ and so on.
Many people feel also some great significance which they cannot properly grasp; when they try to verbalize it, there is nothing to lay hold of.
But it can give some idea that ordinary experience is partly a mental construct, and this is a help in practising yoga.
