Bhagavad Gita: Mediate upon Me within the heart and make Me the ultimate goal of life. (Dhyana-yoga (Text 13,14, Ch 6))

Sri-bhagavan uvaca

Samam kaya-siro-grivam
dharayann acalam sthirah
sampreksya nasikagram svam
disas canavalokayan

prasantatma vigata-bhir
brahmacari-vrate sthitah
manah samyamya mac-citto
yukta asita mat-parah

Meaning: One should hold one's body, neck and head erect in a straight line and stare steadily at the tip of the nose. Thus, with an unagitated, subdued mind, devoid of fear, completely free from sex life, one should  mediate upon Me within the heart and make Me the ultimate goal of life.
