But when the mind acquires the complete habit of this state in which it becomes identified with these fine objects—the tanmātras—etc., then all conceptual notions of the associations of time, space, causality, etc., spoken of in the savicāra and the savitarka state vanish away and it becomes one with the fine object of its communion. These two kinds of prajñā, savicāra and nirvicāra, arising from communion with the fine tanmātras, have been collocated under one name as vicārānugata. But when the object of communion is the senses, the samādhi is called ānandānugata, and when the object of communion is the subtle cause the ego (asmitā), the samādhi is known as asmitānugata.
There is a difference of opinion regarding the object of the last two varieties of samādhi, viz. ānandānugata and asmitānugata, and also about the general scheme of division of the samādhis. Vācaspati thinks that Yoga-sūtra I. 41 suggests the interpretation that the saṃprajñāta samādhis may be divided into three different classes according as their objects of concentration belong to one or other of the three different planes of grāhya (external objects), grahaṇa (the senses) and grahītṛ (the ego). So he refers vitarka and vicāra to the plane of grāhya (physical objects and tanmātras), ānandānugata to the plane of grahaṇa (the senses) and asmitānugata to the plane of grahītṛ. Bhikshu, however, disapproves of such an interpretation. He holds that in ānandānugata the object of concentration is bliss (ānanda) and not the senses. When the Yogin rises to the vicārānugata stage there is a great flow of sattva which produces bliss, and at this the mind becomes one with this ānanda or bliss, and this samādhi is therefore called ānandānugata. Bhikshu does not think that in asmitānugata samādhi the object of concentration is the ego. He thinks that in this stage the object of concentration is the concept of self (kevalapurushākārā saṃvit) which has only the form of ego or “I” (asmītyetāvanmātrākāratvādasmitā).
Again according to Vācaspati in addition to the four varieties of savitarka, nirvitarka, savicāra and nirvicāra there are two varieties of ānandanugata as sānanda and nirānanda and two varieties of asmitānugata as sāsmita and nirasmita. This gives us eight different kinds of samādhi. With Bhikshu there are only six kinds of samādhi, for he admits only one variety as ānandānugata and one variety as asmitānugata. Bhikshu’s classification of samādhis is given below in a tabular form (see Vācaspati’s Tattvavaiśāradī and Yoga-vārttika, I. 17, 41, 42, 43, 44).
(with association of name and concept of the tanmātras) 4. nirvicāra (without association of name, etc.)'
Through the nirvicāra state our minds become altogether purified and there springs the prajñā or knowledge called ṛtambharā or true; this true knowledge is altogether different from the knowledge which is derived from the Vedas or from inferences or from ordinary perceptions; for the knowledge that it can give of Reality can never be had by any other means, by perception, inference or testimony, for their communication is only by the conceptual process of generalisations and abstractions and these can never help us to affirm anything about things as they are in themselves, which are altogether different from their illusory demonstrations in conceptual terms which only prevent us from knowing the true reality. The potency of this prajñā arrests the potency of ordinary states of consciousness and thus attains stability. When, however, this prajñā is also suppressed, we have what is called the state of nirvīja samādhi, at the end of which comes final prajñā leading to the dissolution of the citta and the absolute freedom of the purusha.
Samādhi we have seen is the mind’s becoming one with an object by a process of acute concentration upon it and a continuous repetition of it with the exclusion of all other thoughts of all kinds. We have indeed described the principal stages of the advancement of samprajñāta Yoga, but it is impossible to give an exact picture of it with the symbolical expressions of our concepts; for the stages only become clear to the mental vision of the Yogin as he gradually acquires firmness in his practice. The Yogin who is practising at once comes to know them as the higher stages gradually dawn in his mind and he distinguishes them from each other; it is thus a matter of personal experience, so that no teacher can tell him whether a certain stage which follows is higher or lower, for Yoga itself is its own teacher.
Even when the mind is in the samprajñāta state it is said to be in vyutthāna (phenomenal) in comparison with the nirodha state, just as the ordinary conscious states are called vyutthāna in comparison with the samprajñāta state; the potencies of the samprajñāta state become weaker and weaker, while the potencies of the nirodha state become stronger and stronger until finally the mind comes to the nirodha state and becomes stable therein; of course this contains within itself a long mental history, for the potency of the nirodha state can become stronger only when the mind practises it and remains in this suppressed condition for long intervals of time. This shows that the mind, being made up of the three guṇas, is always suffering transformations and changes. Thus from the ordinary state of phenomenal consciousness it gradually becomes one-pointed and then gradually becomes transformed into the state of an object (internal or external), when it is said to be undergoing the samādhi pariṇāma or samādhi change of the samprajñāta type; next comes the change, when the mind passes from the samprajñāta stage to the state of suppression (nirodha). Here also, therefore, we see that the same dharma, lakshṇa, avasthāpariṇāma which we have already described at some length with regard to sensible objects apply also to the mental states. Thus the change from the vyutthāna (ordinary experience) to the nirodha state is the dharmapariṇāma, the change as manifested in time, so that we can say that the change of vyutthāna into nirodha has not yet come, or has just come, or that the vyutthāna state (ordinary experience) exists no longer, the mind having transformed itself into the nirodha state. There is also here the third change of condition, when we see that the potencies of the samprajñāta state become weaker and weaker, while that of the nirodha state becomes stronger and stronger. These are the three kinds of change which the mind undergoes called the dharma, lakshaṇa and avasthā change. But there is one difference between this change thus described from the changes observed in sensible objects that 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.
