The illusioned living entity appears in so many forms offered by the external energy of the Lord. While enjoying in the modes of material nature, the encaged living entity misconceives, thinking in terms of “I” and “mine.”
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
बहुरूप इवाभाति मायया बहुरूपया । रममाणो गुणेष्वस्या ममाहमिति मन्यते
bahurūpa ivābhāti māyayā bahurūpayā | ramamāṇo guṇeṣvasyā mamāhamiti manyate
