@Pusp sir,
:+1: There are nothing like any do's, dont's and any rituals to follow in this meditation.
:+1: The instructions are already guided by Sharat sir during this meditation as to sit, lay down or to fold, not fold legs. You can please follow according to your body comfort in which you can sustain 30 minutes easily.
:+1: For your other query yes sir you can take energy of KUNDALINI MEDITATION by Sharat sir by VK with mimicking ability.
:+1: Sir My Suggestion is must do this or any meditation physically to experience the Bliss and Vibrations, Energies Sensations in your Body.
:+1: KUNDALINI also knows known as serpent is actually 'kund' ( storage ) of energy below Base chakra (root chakra )
When kundalini rises through Base chakra to all chakras and finally to Crown chakra
It open up all the chakras and cleans whole Energy channels from end of spine to the Crown chakra.
It is said that after this KUNDALINI ACTIVATION a person tends to be live in SUPREME BLISS of LORD SHIVA.
A person becomes highly spiritual being with all psychic abilities clairvoyance, third eye are activated. However nowadays people claim kundalini activated but for my opinion SUN don't need to tell people that i am sun.
SPIRITUALLY "LORD SHIVA" represent the process of Kundalini.
:+1: FOR MY PERSONAL EXPERIENCE
i do this kundalini meditation or any Other meditation 'empty stomach' reason is then my body is completely free to feel energy sensations and vibrations. otherwise body is already consuming energies for digestion process.
