To think that techniques will bring about liberation is small minded and ridiculous. Liberation is when you as a person are absorbed by the Supreme Person.
The first Creator "Brahma" had knowledge of the Supreme Person and it is only those who in turn are possessed completely by the Supreme Person who attain immortality (Liberation)...
Any egocentric activity such as the practice of kriya yoga techniques is tapas (worship).
There is no other way for spiritual perfection (liberation) then to be possessed entirely by the One Supreme Being!
Open your heart and mind to the Infinite One and pray for mercy and purity!
