If you want to enter Samadhi quickly, cut off all connections with friends, relatives, etc. Do not write letters to anybody. Observe Akhanda Mouna or the vow of continued silence for one month. Live alone. Walk alone. Take very little but nutritious food; live on milk alone if you can afford. Plunge in deep meditation. Dive deep. Have constant practice. You will be immersed in Samadhi. Be cautious. Use your common sense. Do not make violent struggle with the mind. Relax. Allow the divine thoughts to flow gently in the mind.
