Vidura’s Questions on Devotion and Sarga; Maitreya Begins the Account of Creation
अहंतत्त्वाद्विकुर्वाणान्मनो वैकारिकादभूत् । वैकारिकाश्च ये देवा अर्थाभिव्यञ्जनं यत: ॥ ३० ॥
ahaṁ-tattvād vikurvāṇān mano vaikārikād abhūt vaikārikāś ca ye devā arthābhivyañjanaṁ yataḥ
The false ego is transformed into mind by interaction with the mode of goodness. All the demigods who control the phenomenal world are also products of the same principle, namely the interaction of false ego and the mode of goodness.
False ego interacting with the different modes of material nature is the source of all materials in the phenomenal world.
This verse says the mind is produced from the transformation of false ego in the mode of goodness (vaikārika/sāttvika ahaṅkāra).
They are the presiding demigods connected with the senses, arising from sāttvika false ego and enabling the expression and recognition of sense-objects.
It reminds a seeker that mind and sense-perception are products of material nature; by cultivating sāttvika discipline and bhakti, one can regulate the mind rather than be ruled by it.
