Every time I try to read Bhagwat Gita I feel confused. It feels like I have to follow life with restrictions. Like we can't have the desire, should not think of the result, wrong to have the material desire. Could you tell me how can I understand Gita?
There are four goals of life according to Hinduism. These goals are dharma, artha (wealth), kama (desire) and moksha. Gita is for those who are fed up with artha and kama and want to attain moksha. Who are the people who want to attain moksha? They are people who think of this world as a vale of sorrow.
Ocean of Life – Need for Moksha
"That Ocean, so terrible has sorrow for its waters. Anxiety and grief constitute its deep lakes. Disease and Death are its gigantic alligators. The great fears that strike the heart at every step are its huge snakes. The deeds inspired by Tamas are its tortoises. Those inspired by Rajas are its fishes. Wisdom constitutes the raft for crossing it. The affections entertained for objects of the senses are its mire. Decrepitude constitutes its region of grief and trouble. Knowledge..is its island. Acts constitute its great depth. Truth is its shores. Pious observances constitute the verdant weeds floating on its bosom. Envy constitutes its rapid and mighty current. The diverse sentiments of the heart constitute its mines. The diverse kinds of gratification are its valuable gems. Grief and fever are its winds. Misery and thirst are its mighty eddies. Painful and fatal diseases are its huge elephants. The assemblages of bones are its flight of steps and phlegm is its froth. Gifts are its pearl-banks. The lakes of blood are its corals. Loud laughter constitutes its roars. Diverse sciences are its impassibility. Tears are its brine. Renunciation of company constitutes the high refuge (of those that seek to cross it). Children and spouses are its unnumbered leeches. Friends and kinsmen are the cities and towns on its shores. Abstention from injury and Truth are its boundary line. Death is its storm-wave. The knowledge of Vedanta is its island (capable of affording refuge to those that are tossed upon its waters). Acts of compassion towards all creatures constitute its life-buoys, and Emancipation is the priceless commodity offered to those voyaging on the waters in search of merchandise. "

If you think that this world is a mansion of mirth and the above passage describing this world a vale of tears is over the top then you should go for artha and kama and Gita which is a moksha sastra is not for you.

It will clear many confusions and also help me much.
One caveat: It is not to be read as only but with book of Bhagavad Gita as it is. And sorry if someone is disagree with it.
