In my opinion, on the crop circle through figures and numbers are depicted following energies according to the Mayan calendar:

White Wizard – Solar Seal of the actual Solar year of 365 days,
Yellow Seed – the Challenging energy of the White Wizard,
Yellow Sun – Solar Seal of the day 1.08.2007,
Yellow Warrior – the major energy of the actual White Castle,
White Worldbridger – Challenging energy of the Yellow Warrior

These energies have following short characteristics:

White Wizard – Timelessness, Receptivity, Enchantment
Yellow Seed - Targeting, Flowering, Awareness
Yellow Sun – Enlightenment, Ascension, Universal Fire, Life
Yellow Warrior – Explore, Intelligence, Fearlessness
White Worldbridger – Equalizing, End, Death, Opportunity

On 26^th July 2007 began the Year of the White Lunar Wizard, with Tone 2, Kin 54 in the Tzolkin calendar.

In the center of the crop circle we see 18 figures, with 3 rhombs each, or these are 54 rhombs in total.

Here the number 54 symbolizes the actual White Lunar Wizard Year with Kin 54.

1^st August 2007 is a day with the Solar Seal “Yellow Sun”.

And on the crop circle we see 4 rings of triangles, which look like sun rays, and in whole, they really look like a wonderful SUN !!

1^st August 2007 (this is Kin 60) is a day of the White Castle, when we receive and have the possibility to learn the energy “Yellow Warrior”.
On each of the 4 rings there are 36 triangles.
The number 36 symbolizes the Solar Seal “Yellow Warrior”.

In the Tzolkin calendar, Kin 36 is with the Solar Seal “Yellow Warrior”.

The total number of the triangles on the 4 rings is:

4 х 36 = 144

Kin 144 in Tzolkin is with the Solar Seal “Yellow Seed”.
The “Yellow Seed” is the Challenging energy of the White Wizard, which is the Solar Seal of the actual year.

In the center of the crop circle we see a 6 pointed star. It symbolizes the Solar Seal White Worldbridger, which is Solar Seal No. 6. The White Worldbridger is very important energy in the White Castle, it is the Challenging energy of the Yellow Warrior.
