I know at the top of the watchtowers meditation it says that it's out of date, but that's apparently only in reference to the mantras given and not which 3 chakras constitute the granthis.
I'm not trying to nitpick the site I only want clarity.

The three "knot" chakras referred to in Sanskrit are the base, the heart [the major knot chakra] and the sixth, behind the third eye

Given the experiences of many, it appears that the three granthis [knots where the chakra concerned has a powerful energy block that prevents the serpent from ascending] are not at the base, heart, and sixth chakras as popularly taught, but are at the second [sacral] chakra, the throat chakra, and the crown chakra. There have been many accounts of one's heart chakra feeling a burning sensation; as the serpent cannot ascend any further due to a blocked throat chakra.
