Chitta

Total mind, mental field. In YS 1.2, yogaḥ citta-vṛtti-nirodhaḥ: yoga is the stilling of the [[vritti|fluctuations]] of citta. In Sāṃkhya, citta encompasses manas (thinking mind), ahaṅkāra (ego), and buddhi (intellect). It is the mirror in which puruṣa is reflected — and also the veil that obscures it when identified with its own modifications.
