Mandukya Karika, verse 2.14


चित्तकाला हि येऽन्तस्तु द्वयकालाश्च ये बहिः ।
कल्पिता एव ते सर्वे विशेषो नान्यहेतुकः ॥ १४ ॥

cittakālā hi ye'ntastu dvayakālāśca ye bahiḥ |
kalpitā eva te sarve viśeṣo nānyahetukaḥ || 14 ||

14. Those that are cognized within only as long as the thought of them lasts, as well as those that are the senses and that conform to two points of time, are all mere imaginations. There is no other ground for differentiating the one from the other.

Shankara Bhashya (commentary)

A1 doubt is raised as to the statement that everything is mere imagination of mind like the dream. For, the imagination of mind, such as desire, etc., determined2 by mind, is different from objects3 perceived to exist outside, on account of the latter being determined by two points in time. This objection is not valid. Objects perceived to exist within, only as long as the thought About them lasts, signify those (subjective) ideas which4 are only determined by mind; i.e., such objects have no other time to determine them except that wherein the idea in the mind exists (when.imagining such ideas). The meaning is that such (subjective) ideas are experienced at the time when they are imagined. Objects related to two points of time signify those external objects which are cognizable by others at some other point of time and which cognize the latter in their turn. Therefore such objects are said to be mutually limited by one another. As for example, when it is said that he remains5 till the cow is milked, the statement means, “The cow is milked as long as he remains and he remains as long as the cow is milked.” A6 similar instance is the following: “It is like that, that is like this.” In this way, the objects perceived to exist outside mutually determine one another. Therefore they are known as “Dvayakālāh” that is, related to two points in time. Ideas perceived within and existing as long as the mind that cognizes them lasts, as well as the external objects related to two points in time, are all mere imaginations.7 The8 peculiar characteristic of being related to two points in time of the objects that are perceived to exist outside is not due to any other cause except their being imagined by the mind. Therefore the illustration of dream well applies here.
