Sahasrara, Nirvana and Manolaya in the above table have more or less the same significance, as it is here that the Yogi attains liberation and his mind is absorbed in the Parampada.
Another point of interest is that the Kundalini in the Nabhi- cakra is stated to have five coils instead of the usual eight.
The sixteen adharas (supports) on which the mind is to be fixed for attainment of different results are described. The three laksyas or points of concentration and the five vyomans (firmaments) lead one to various stages of purity and perfection. The asanas (postures) and the eight Yogangas (different stages of Yoga) all help the Yogi in attaining Samadhi (i. e. fixation of the mind on the Supreme Spirit).
In this Chapter there is a definition of the real Yogi, (2. 61).
नवचक्रं कलाधारं त्रिलक्ष्यं व्योमपञ्चकम् ।
सम्यगेतन्न जानाति स योगी नामधारकः॥ ३१ ॥
i.e., One must be familiar with the nine cakras, sixteen adharas, three lakyas and five vyomans properly in order to be a Yogi in the true sense.

In (2.27) we find 'Gollata' (Hardwar copy) or 'Kollata' in (Jodhpur copy) mentioned. The nine khandas (Bharat, Kashmir etc.) are in the nine avenues. The hills, rivers, planets, devas, siddhas, the sun and the moon (these are the two eyes), clouds (these are the tears), creepers, plants &c. have their counterparts in the human body. What is our happiness is Heaven, our sorrow is Hell, our Karma is what binds us to this world, but for which we may attain Mukti i.e. liberation. When ones mind does not
