Meher ki class farsh par bhautik naksha bichhaakar Bharat ke upar ek kaalpanik udaan ki yojana banaati. "Rang oonchaai dikhaate," teacher legend dikhaakar kehti. Bharat duniya ka saatvaan sabse bada desh. Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka aur Myanmar ke saath ye Bharatiya Upmahaadweep banaata. Hum paanch kshetron ke upar udenge: pahaad, uttari maidaan, registaan, dakshini prayadweep aur dweep.
Uttar mein Himalaya lagbhag 2500 km lambi deewaar jaise, chhah deshon mein faila. Kai shikhar 8000 m se oonche. Bahut pehle Bharat Gondwana naam ke bhoo-bhaag ka hissa tha; wo toot kar uttar khiska aur lagbhag 5 crore saal pehle Eurasia se takraaya. Beech ki zameen dhakeli dari ki tarah sikud kar uthi. Bharat ab bhi saal mein lagbhag 5 cm uttar dhakelta, to Himalaya har saal kuch millimetre oonche hote.
"Himalaya" matlab barf ka ghar. Garmi mein pighalti barf Ganga, Sindhu aur Brahmaputra bharti, isliye ise Asia ka Jal Stambh kehte; Bhagirathi Gangotri hims-nadi ke kinaare Gaumukh se shuru hoti. Teen shrinkhalaayein: barfeeli Himadri jismein Everest aur Kanchenjunga; Himachal jismein Shimla aur Darjeeling jaise hill station; aur neechi jangali Shivalik. Patthar-lakdi ke kath-kuni ghar garam rehte aur halke bhookamp sehte.
Har registaan garam nahi. Ladakh thanda registaan hai: bahut kam baarish aur –30 °C se neeche sardi. Iski pathreeli "moonland" kabhi samudra tal thi jo mahaan takkar mein mudkar uthi. Khaari Pangong Tso yahin (tso matlab jheel). Hims tendue, ibex aur yak in oonchaaiyon mein; yak doodh, oon aur gobar dete aur bojh dhote. Math aur Losar aur Hemis jaise tyohaar lambi sardiyon ko roshan karte.
