Ch. 15 Yoga of meditation on the root of the aśvattha (part 3)
We saw in the previous Bhāgavata śloka a mention of two birds in the primordial tree - dvikhago hyādivṛkṣaḥ. When there is a tree, there is usually a bird in it. The metaphor of the two birds comes to us again from the Veda. The Muṇḍakopaniṣad describes the two birds of the saṃsāra tree thus.
dvā suparṇā sayujā sakhāyā samānaṃ vṛkṣaṃ pariṣasvajāte ||
Muṇḍakopaniṣad 3.1.1
