Here are some of the methods to get a glimpse of Samadhi. Each one has its own merits and de merits.
1. Drugs (Psychedelics)
2. Mantra ( a sound, syllable, word, or group of words that are considered capable of "creating transformation").
3. Performing Austerities.
I will write about each of them someday. But as of now I will change gears and post some other stuff. This post I will complete later.
