“Concerning the number of Cakra, we also find different ideas. The most frequent is that which considers there to be seven. However in his book ‘Yoga Makaranda‘ my father talks of ten. There are other ideas as to the number elsewhere, the form in which they are visualised varies according to tradition.
Many Yogins visualise them as circles or wheels. According to other sources, they are described as lotuses or Padma with varying number of petals. Compared to the idea of a wheel, which evokes more the idea of movement and rotation, the lotus evokes more the idea of creation.
If we analyse all this seriously, we see, in the respect of the Cakra, that the sages, during meditation, did not always have the same experiences and visions. There is no need to discuss this, because it depends on the personal experience of each seer. However, it is important to be aware of these differences and the consequences that they can have for the way in which we imagine the experience.”
