Make an Offering to the Kalachakra Deity 

According to Khentrul Rinpoche: Flower offerings to Kalachakra are best for more general and broad benefits. Every week we change the flowers in the temple at the Rime Institute including in front of Kalachakra. Your offering directly enables this to happen.

Benefits of offering flowers in general
It is helpful to remind ourselves that the benefits below may not ripen immediately. Think that we are generating conditions for them to ripen. From the sutra Distinguishing the Aspects of Karma (Lanam Je): There are ten benefits of offering flowers [to objects such as the buddhas, statues, stupas, scriptures, etc.]:

1. One becomes like a flower in the world. (You will be very beautiful; everyone will be attracted and amazed to look at you and will remember seeing you.)
2. The sense of smell will never degenerate. (Some people have sicknesses in the nose so that the sense of smell doesn’t function.)
3. One will never have bad body odor. (This will be completely purified.)
4. A smell of scented nectar will come from the body.
5. The smell of the morality of the person will spread in all directions and corners.
6. One will be a leader of the world. (One will be a leader of people, of the world, of holy beings.)
7. One will achieve beautiful attractive things.
8. One will have great wealth.
9. One will be reborn in a higher rebirth.
10. One will quickly achieve the sorrowless state and achieve enlightenment, the great liberation.
