To sit in lotus posture (padmasana) and make the Kundalini shakti(spiritual energy) rise from the Mooladhara (basal plexus) to the Sahasrara (the node in the crown of the head) is not dhyana(meditation). True Meditation consists in recognising the presence of God in all types of work you do in your daily life. God is the indweller of all. To attempt to confine God to one place you choose is not meditation! According to our culture, we first pay obeisance to the work we have to do. Before we undertake any work, we should regard that work as God. That is what the Upanishads teach us, “Tasmai Namaha Karmane – I salute the work I have to do and adore God in that form”. Have you seen a person who plays on the tabla or the harmonium? Before they begin to play on it, they pay obeisance to the instrument. To regard the entire creation as the form of God and to perform your duty in that spirit, is true meditation.
