Off late adi has been practising this theory very ably with his index finger. Theory came into being when adi realized the word "dao" n index finger can do wonders for him. for ex. when he says dao n points to the door with his tini mini index finger it means its time to go for a walk..... be it eve or morning a walk is a must for little baby's health...... also dao n index finger towards wht ur eating means he wants to eat wht ever ur eating n god save u if u refuse to gv him on his health n age grounds coz nw he knws one year babies should eat well...... dao n index finger towards a person means nw tht person should hold him in his arms n thank lord for the opportunity gvn....... dao n index finger towards u also means tht he's upset with u n conveying his displeasure....... so these r just few ways of using dao theory........ i think adi is again saying dao dao.....
