Usha means the early morning dawn of colour on the eatern horizon. Water taken early morning as you get up from the bed at the rise of dawn is given the name of ‘Usha Paan’, the drink of the dawn.
For this purpose, about one litre or less (say two-and-a-half glasses of water) is kept in a copper vessel at night while going to bed. The water is better kept in the pot for the whole night in the open to be sufficiently cool in the morning.
In winter it may be kept inside. As you get up in the morning, drink this lot of water, after washing your mouth. This water serves like nectar ‘amrit’ to man. It has its own taste, if taken from a copper vessel.
This helps in the proper clearing of the bowels and with so much of water taken you do not feel any urge for tea and can easily go without your bed tea, which is not a good thing in Nature-cure.
