The consciousness of an object is attained by concentration upon its fourfold nature : the form , through examination ; the quality ( or guna ) , through discriminative participation ; the purpose , through inspiration ( or bliss ) ; and the soul , through identification 自性意识（真我）经由集中冥想于四个自然属性而获得：观想（物相） 、明辨（性质） 、相应（灵佑） 、融合（皈依） 。

In hindu tantra , practice is graded into three types , corresponding to three classes of devotees : the animal , i . e . , those in whom the guna , or quality , of tamas ( darkness ) predominates ; the heroic , those in whom the guna of rajas ( activity ) predominates ; and the divine , those in whom sattva ( goodness ) predominates ( see hindu philosophy ) 在印度教坦陀罗，练习被分成三种类型，与三种级别的皈依者相对应：动物，那些在黑暗之中，或者等同于黑暗支配的人；英雄，那些掌握主动支配的人；和神性，那些有良好支配的人（看看印度哲学） 。
