A complex practice of meditation that helps overcome the harmful effects of karma and helps you attain enlightenment to benefit others is called Kalachakra. It is a practice from the deepest levels of tantra, anuttarayoga. There is a whole encyclopedia of ancient Indian science incorporated in the literature of this technique that benefits people despite them having different beliefs.
In literal meaning, “Kalachakra” implies the cycles of time. Here, time is the measure of both internal (bodily) and external (worldly) changes that can be gauged in several ways.
To measure external change, the orbit cycles of the planets, the seasons and months a year, hours of the day, different phases of the moon, etc. are used. Even the periods of war and peace and other historical cycles can be used to measure external change
As for the internal changes, cycles related to the periods of life including the formative years, babyhood, adolescence, adulthood, and senior age, sleep patterns, the menstrual and circadian cycles, breath per day etc. are taken into account.
Both the external and internal cycles parallelized each other and both of them are recurring endlessly with the long-lasting reincarnation of the universes and lifetimes.

The ‘Alternative Kalachakra’
A cycle of empowerment or tantric initiation where there are two stages, i.e. practice and attainment of Buddhahood, is called “alternative Kalachakra”. This cycle, in addition to being an alternative to both the internal and external kalachakras, is the ultimate cure for those who are under the detrimental influence.
What is So Unique about Kalachakra
Kalachakra is unique not in one but in numerous ways. The literature of it contains complex mathematical rules and formulae that allow people to calculate the position of the planets, sun, and the moon, the length of the days, eclipses’ timings, lunar calendar, and of course, the astrological horoscopes.
It also entails engineering information to manufacture useful mechanical devices in times of peace and war. There are elaborated scripts of the internal cycles that contain the descriptions of the body’s energy system with its drops, channels, and chakras, in addition to several aspects that are integrated into the Tibetan medical tradition and used as an analysis of Sanskrit phonetics.
Summing Up
Kalachakra is rather an extremely advanced and elite technique that has been benefiting numerous people out there. There are forms of mandalas that are less complicated and contain fewer figures than the complex ones and yet they are challenging to abbreviate. It is, in fact, safe to say that Kalachakra itself is a very challenging practice. However, the effects of achieving enlightenment to benefit humans around can be received using the correct motivation and an effort that is well-prepped and lasting.
There are traditions in which Kalachakra initiation, dissimilar to other complex tantras, is given to large groups of people in the wake of promoting peace and harmony in the world.
The first one-of-its-kind initiation was given by His Holiness the Dalai Lama in the year 1954 in the Lhasa region of Tibet. Factually speaking, there are about 2 million people who have been a part of the Kalachakra initiations that the Dalai Lama gave worldwide.
