After getting up from the sleep, kardarshan (viewing the palm of the hand) should be done.
Karagre Vasate Lakshmi, Karmadhye Saraswati
Karmule tu Govind, Prabhate kardarshanam
कराग्रे वसते लक्ष्मी, करमध्ये सरस्वती
करमूले तु गोविन्दः, प्रभाते कर दर्शनम्
On the tip of your fingers is Goddess Lakshmi; on the base of your fingers is Goddess Sarasvati; in the middle of your fingers is Lord Govinda. In this manner, look at your palm.
Laxmi, Saraswati and Govind reside on the palm, so one should bow to them with respect, this is the logic behind kardarshan. Of course, with common sense point of view, to get hold of Lakshmi (money) and Saraswati (knowledge) is in our hands only, to remind one of this principle is the main logic behind kardarshan.
