here the changes are not visible but are only to be inferred by the passage of the mind from one state to another. It has been said that there are two different kinds of qualities of the mind, visible and invisible. The visible qualities whose changes can be noticed are conscious states, or thought-products, or percepts, etc. The invisible ones are seven in number and cannot be directly seen, but their existence and changes or modifications may be established by inference. These are suppression, characterisation, subconscious maintenance of experience, constant change, life, movement and power or energy. In connection with samprajñāta samādhi some miraculous attainments are described, which are said to strengthen the faith or belief of the Yogin in the processes of Yoga as the path of salvation. These are like the products or the mental experiments in the Yoga method, by which people may become convinced of the method of Yoga as being the true one. No reasons are offered as to the reason for these attainments, but they are said to happen as a result of mental union with different objects. It is best to note them here in a tabular form. ─────────────────────────────────┬────────┬──────────────────────────── Object of Saṃyama. │Saṃyama.│ Attainment. ─────────────────────────────────┼────────┼──────────────────────────── (1) Threefold change of things │Saṃyama.│ as dharma, lakshaṇa and │ │ avasthāpariṇāma. │ │ (2) The distinctions of name, │ „ │Knowledge of the sounds of external object and the │ │ all living beings. concept which ordinarily │ │ appears united as one. │ │ (3) Residual potencies saṃskāra │ „ │Knowledge of previous life. of the nature of dharma │ │ and adharma. │ │ (4) Concepts alone (separated │ „ │Knowledge of other minds. from the objects). │ │ (5) Over the form of body. │ „ │Disappearance (by virtue of │ │ perceptibility being │ │ checked).
