Why Bramha who is self-born i.e. manifested on its own as per Yoga Vasistha, also called Lotus born as per Yoga Vasistha? What is the meaning of lotus here? Is it simple flower or something else very deep?
असत्य एव कचति स्वप्ने खोड्डयनं यथा ।
इत्यनुत्पन्न एवासौ स्वयंभूः स्वयमुत्थितः ॥ ३८ ॥
3.13.38 The unproduced and self-born Brahma, that has risen of himself (and represents the mind), is as unreal as the soaring of a man in the sky in his dream.
कृत्वा पद्मजसंकल्पं रूपं पश्यति पद्मजम् ।
ततो जगत्कल्पयति सप्रजापतिपूर्वकम् ॥ ८ ॥
4.40.8 Taking the conception of the lotus-born, it finds itself in its conceived form of the lotus (Brahma), and then it thinks of creation in the form of Prajapati or lord of creatures.
