MEDITATE, MEDITATE, MEDITATE. Leave the identity of the meditator and melt into the Silence / Stillness that is ever present. Stop Seeking till you find it.
sanātana (सनातन) means the one which is existing since the beginning. And, the one that is existing since the beginning is avyakta (in-expressible or the Unmanifested) or Nothing-ness. Hence, sanātana dharma (सनातन धर्म) is that by which we get into the awareness of Nothing-ness.
Meditation is the process where the individual "i" melts into the universal "I" and reveals the awareness that there is only One which is present and nothing else.
