I know that Rudraksha beads are divine beads, Lord shiva's tears and helps in spiritual empowerment. Since then, I have started chanting mantras on a Japa Mala as chanting mantras on a Rudraksha Malas helps in activation of Chakras. But for detailed study of Chakra activation I need to sit in a state of 'Samadhi'. But what actually is 'state of Samadhi'? or is there any other way by which I can Practice meditation for keeping my 7 chakras balanced ?If anyone can help on this I will be of great help.
