Sri Raju Sastrigal asked Sri Bhagavan about nada , bindu and kala .
Maharshi: They are in Vedanta terminology prana, mana, buddhi (the life-current, mind and intellect). In the Tantras nada is said to be subtle sound with tejas - light - in it. This light is said to be the body of Siva. When it develops and sound is submerged, it becomes bindu. To be full of light (tejomaya ) is the aim. Kala is a part of the bindu.
