ध्यानं हि निश्चला बुद्धिर्निराकारा निराश्रया । न तु ध्यानं शरीराक्षिमुखहस्तादिकल्पना ॥ १४६ ॥
When the intellect becomes steady, formless and without any support, meditation is verified. Imagination of the form of the divine with a body, eyes, mouth, hands, etc. is not meditation.
पूजा नाम न पुष्पाद्यैर्या मतिः क्रियते दृढा । निर्विकल्पे महाव्योम्न्नि सा पूजा ह्यदरालयः ॥ १४७ ॥
Offering of flowers, etc. is not pooja, or worship, but making one's mind steady in mahakasha, the great void, (and thoughtless) in nirvikalpa is worship indeed. From such reverence, dissolution (of mind) takes place.
By being established in any one of the practices (described) here, whatever (experience) is produced, develops clay by day until the state of absolute fullness or satisfaction is attained.
The real oblation is (made) when the elements and sense perceptions along with the mind are poured as oblation into the fire of the great void (i.e. bhairava or supreme consciousness) using the consciousness as a ladle.
