The anniversary of the day 
on which Lord Krsna spoke the Bhagavad-gita

The following verses from the Bhagavad-gita (10.8-11) are known as the "nutshell" verses of the Gita, because they contain the essence of Lord Krsna's teachings in that great transcendental work.

aham sarvasya prabhavo
mattah sarvam pravartate
iti matva bhajante mam
budha bhava-samanvitah

I am the source of all spiritual and material worlds. Everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts.

mac-citta mad-gata-prana
bodhayantah parasparam
kathayantas ca mam nityam
tusyanti ca ramanti ca

The thoughts of my pure devotees dwell in Me, their lives are fully devoted to My service, and they derive great satisfaction and bliss from always enlightening one another and conversing about Me.

tesam satata-yuktanam
bhajatam priti-purvakam
dadami buddhi-yogam tam
yena mam upayanti te

To those who are constantly devoted to serving Me with love, I give the understanding by which they can come to Me.

tesam evanukampartham
aham ajnana-jam tamah
nasayamy atma-bhava-stho
jnana-dipena bhasvata

To show them special mercy, I, dwelling in their hearts, destroy with the shining lamp of knowledge the darkness born of ignorance.
