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).
