Bodhicitta, the aspiration to attain enlightenment in order to benefit all sentient beings, is something that is truly inconceivable, truly splendid and marvellous. One of the great gurus of Lama Atisha told him that an attainment such as clairvoyance, or a vision of a deity, or concentration as stable as a mountain is nothing compared to bodhicitta. For us, these attainments seem amazing. If we ourselves, or if someone we heard of, had a visioon of a deity, achieved clairvoyance, or through practising meditation attained concentration as stable as a mountain, we would think this to be unbelievably wonderful. However, Atisha's guru said to him: "These are nothing compared to bodhicitta. Therefore, practise bodhicitta.
