Yuganadha
yuganaddha : (adj.) congruous; harmonious; connected to a yoke. Yuganaddha A method of meditative practice where, in alternating sequence, tranquillity-meditation and insight-meditation are developed.
It is called 'tranquillity and insight joined in pairs' samatha-vipassanāyuganaddha the coupling or yoking of tranquillity and insight. He who undertakes it, first enters into the 1st absorption.
After rising from it, he contemplates the mental phenomena that were present in it feeling, perception, etc. as impermanent, painful and no-self, and thus he develops insight.
Thereupon he enters into the 2nd absorption; and after rising from it, he again considers its constituent phenomena as impermanent, etc.
In this way, he passes from one absorption to the next, until at last, during a moment of insight, the intuitive knowledge of the path of Stream-entry, etc. flashes forth - See A. IV, 170; A.IX, 36; Pts: Yuganaddha Kathā.
s. samatha-vipassanā, last paragraph.
Ananda tells the monks at Ghositarama, in Kosambi, that those who have attained arahantship have done so in one of four ways:
by developing insight preceded by calm,
or calm preceded by insight,
or calm and insight together,
or by having a mind utterly devoid of perplexities about the Dhamma. A.ii.157.
