The top image represents the state above the Sahasrara Chakra called Pralaya, the dissolution of the universe before it is recreated.
The sage Markandeya is shown worshipping Lord Vishnu in the form of an infant sucking his toe (symbolising the sweetness of surrendering to the Lotus Feet of the Divine). All that exists is The Self (Lord Vishnu), the ocean of existence (pure undifferentiated being), a banyan tree (representing Self-knowledge), and the sage (the witness).
Other images are of some of the chakras.
The bottom image is of the Kundalini, the coiled spiritual energy which connects us with the All-pervading Supreme Self.
