There are 2 funadamental steps of meditation. First is samatha, second is vipassana. Ever lasting happiness can be attained through meditation. If it was not possible, I would recommend you to do drugs, sex, alcohol; but everlasting happiness is possible.
Samatha (Pāli), śamatha (Sanskrit; also orthographically romanized to shamatha) "calm abiding," comprises a suite, type or style of Buddhist meditation or concentration practices designed to enhance sustained voluntary attention, and culminates in an attention that can be sustained effortlessly and for hours on end. Samatha is a subset of the broader family of samadhi ("concentration") meditation practices.
Samatha is a focusing, pacifying and calming meditation, common to many traditions in the world, notably yoga. It is used as a preparation for vipassanā, pacifying the mind and strengthening t he concentration in order to allow the work of insight. This dichotomy is also sometimes discussed as "stopping and seeing." In Buddhist practice it is said that, while samatha can calm the mind, only insight can reveal how the mind was disturbed to start with, which leads to prajñā (Pāli: paññā, wisdom) and jñāna (Pāli: ñāṇa, knowledge) and thus understanding, preventing it from being disturbed again.
