Meditate on OM
by Swami Sivananda
Retire into the meditation chamber. Sit on Padma, Siddha, Svastika or Sukha Asana. Relax the muscles. Close the eyes. Concentrate the gaze on Trikuti, the space between two eyebrows. Repeat OM mentally with Brahma Bhavana. This Bhavana is a sine qua non, very very important. Silence the conscious mind.
Constantly feel-OM OM OM
All-pervading, ocean of light I am-OM OM OM
Infinity I am-OM OM OM
All-pervading, Infinite light I am-OM OM OM
Vyapaka, Paripurna, Jyotirmaya Brahman I am-OM OM OM
Omnipotent I am-OM OM OM
Omniscient I am-OM OM OM
All Bliss I am-OM OM OM
Sat-Chit-Ananda I am-OM OM OM
All Purity I am-OM OM OM
All Glory I am-OM OM OM
All Upadhis will be sublated. All Granthis (heart-knot, ignorance) will be cut asunder. The thin veil, Avarana will be pierced. The Pancha Kosa Adhyasa (superimposition) will be removed. You will rest doubtless in Sat-Chit-Ananda state. You will get highest Knowledge, highest Bliss, highest Realisation, and highest End of life. "Brahmavid Brahman," "Brahmavid Brahmaiva Bhavati." You will become Suddha Sat-Chit-Ananda-Vyapaka-Paripurna Brahman. "Nasti Atra Samsayah." There is no doubt of that, here.
There is no difficulty at all in Atma-Darshan. You can have this within the twinkling of an eye as Raja Janaka had, before you can squeeze a flower with the fingers, within the time taken for a grain to fall when rolled over a pot. You must do earnest, constant and intense practice. You are bound to succeed in 2 or 3 years.
Nowadays there are plenty of "talking Brahmans." No flowery talk or verbosity can make a man Brahman. It is constant, intense, earnest Sadhana and Sadhana alone that can give a man direct Aparoksha Brahmic Realisation (Svanubhava or Sakshatkara) wherein he sees the solid Brahman, just as you see this solid white wall in front of you, and feels the Brahman just as you feel this table behind you.
Note-Study carefully Mandukya Upanishad with Gaudapada's Karika.
