Are Aksobhya and Bhaisajyaguru the same buddha? This page by Venerable Husan Hua says yes; this page by Zhuoge Rinpoche says no.
Apart from both being blue, the iconography of the two Buddha's is completely different - different mudras and implements for example. Their "function" is also different. One represents wisdom (Akṣobhya) and the other compassion (Bhaiṣajyaguru). if they are supposedly the same, then why are they so different?
