Guru jee's Hukam (instruction) to us on commencing of the month of Chet (mid March - mid April):

In the month of Chet (the Spring season arrives, the blossoming of flowers everywhere brings joy to the mind), meditate on Waheguru, the Lord of the Universe, (and through the blessings of doing Simran) a deep and profound spiritual joy can arise. However, meeting with the humble Saints, the gift of chanting Waheguru's Name with our tongue is obtained. Those who have found Waheguru (through the aid of Simran) are blessed in their coming into this world, (because) those who live without Him, for even an instant - their lives are rendered useless. That Lord who is totally pervading the water, the land, and all space, He is contained in the forests as well. Those who do not remember such a Lord (i.e. Waheguru) then that person's mental anguish and suffering cannot be explained. (However,) those who enshrine that (All-prevading) God in their hearts, have great good fortune. My mind yearns for the Blessed Vision of the Lord Waheguru’s Darshan. O Nanak! My mind is so thirsty to have Your Darshan! I will touch the feet of the one who unites me with Waheguru in the month of Chet. 2
