and try to meditate upon it. It has become fashionable to meditate, but people know nothing about the object of meditation. That is explained here.  Yad dhyāyato viṣṇum . One has to meditate upon Lord Viṣṇu or Lord Kṛṣṇa. Without referring to the  śāstras , so-called meditators aim at impersonal objects. Lord Kṛṣṇa has condemned them in  Bhagavad-gītā  (12.5):
kleśo ‘dhikataras teṣām avyaktāsakta-cetasām avyaktā hi gatir duḥkhaṁ dehavadbhir avāpyate
“For those whose minds are attached to the unmanifested, impersonal feature of the Supreme, advancement is very troublesome. To make progress in that discipline is always difficult for those who are embodied.”
Not knowing how to meditate, foolish people simply suffer, and there is no benefit derived from their spiritual activities. The same reference can be found in the following verse from the  Viṣṇu Purāṇa  (6.2.17),  Padma Purāṇa  ( Uttara-khaṇḍa  72.25) and  Bṛhan-nāradīya Purāṇa  (38.97).
